    • Great Keyboard
Style: 2.4G Version
Edit: I've had this thing for about a year and my opinions have not changed. It's a solid mini-keyboard and definitely worth the price, holding up well. Charge lasts 4-6 weeks before having to plug it in. Touchpad has sort of lost its texture from all the use, but still works well enough. Keys are small enough that they're difficult to type on, but finger peckers / typing novices will find it just fine. Charge indicator has never worked, nor has the low battery indicator. It has always just lit up the wireless LED when charger is plugged in. So the only warning it's going to need a charge is when it simply stops working. Not a deal breaker, but hope they fix that in future versions. ORIGINAL REVIEW: I've owned this keyboard for about 6 weeks now and it's an absolute gem for a home theater PC. It's proven durable so far, having four kids tends to put handheld devices through quite a torture test. The backlight LEDs are bright and having the three color options is awesome. I've used plenty of expensive brand name keyboards, and the touchpad on this is among the best. I don't like that there's not physical mouse buttons under the touchpad, but thankfully there is a physical left click button (on the left side of the keyboard) that saves the day. Perfectly usable is how I'd describe it. The keys are small and hard to type on, but nothing worse than what I've experienced on any other small form factor HTPC keyboard. They work just fine otherwise. I really love that the F1-F12 keys are the primary button, and you have to hold down the FN to access the secondary media functions. A lot of HTPC keyboards have this backward where you have to hold FN to use F1-F12 keys at the top, and media keys are the default-- I'm a PC user going back a couple decades, so not having native F1-F12 keys is almost impossible to get used to. This keyboard does it right in my opinion. I'm 6 weeks into it and I haven't had to charge it other than when I first got it. My kids and wife are the primary users and they know to switch the keyboard off (it has a power switch on top) when they're done with it. Switching the power on activates it immediately, I've never had to reconnect the transmitter or do any kind of re-pairing. If you leave it set for awhile with power on, the backlight turns off and seems to go to sleep on its own, but wakes right away with any keypress or mouse movement. It just works every time. The only flaw I've noticed is that when I plug it in to charge, the wireless LED turns on. I can see that there is a low battery indicator, and a battery charge indicator, but I haven't seen the charge LED light up, even with the charger connected. If you have the keyboard switched off or on and plug it into a charger, the wireless LED lights up. I've verified the keyboard is taking a charge by connecting a USB load meter to it in between the keyboard and charger. It draws about 300 milliamps anytime the charger is connected, which tells me it's charging just fine. That said, I've never depleted the battery, so I'm not really sure if the low battery indicator works. But the charging LED certainly doesn't, it turns the wireless LED on instead while charging. Why? I'll never know but since it seems to be charging fine, I won't complain. I'll know for sure when it finally runs dead whether the low battery indicator works, and will try to update this review. In conclusion this is an awesome keyboard and works perfectly for this application. My last keyboard was an expensive Logitech and the charger port broke off a few months in. This keyboard works better and using the touchpad is a much better experience. This has a USB tether for charging (that slips inside a plastic cover) which will likely last a long time if not abused. They also include a USB extension cable in the box so you don't have to put any strain on the short USB tether. The fact there's no charger port to break off is a good thing in my opinion. I really feel like buying a couple more of these just to store away in a closet because I'm sure it won't last forever and they will probably stop making these at some point-- this keyboard is that good that a spare or two would be nice to have and the price is right! ... show more

    • Good for most uses
Style: 2.4G Version
The keyboard works fine and I like the backlight. I just have a couple issues with the trackpad on Windows. Whenever I use the scroll gesture on a webpage, it often zooms in because my fingers move apart slightly when doing the gesture. RII doesn't produce drivers for this, so there is no option to turn off the zoom gesture. The trackpad does have a one-finger scroll area on the right side, so I recommend using that instead of the gesture. The other issue I have is that I can do a left click drag, but when I try to do a right click drag, it performs the zoom gesture. So this trackpad won't work for games or applications where you need to drag something while holding down the right mouse button. ... show more

    • Worth the money, exactly what I needed.
Style: 2.4G Version
Great keyboard. It is a smaller keyboard, so know that. Lights are super bright and fun to use. I’m going to try to address some of the beefs that other reviewers had, because I feel pretty good about this purchase. It’s not super bendy. It’s easy to use in your lap. It doesn’t have to the be on a flat surface. Sure a micro/mini/c usb plug-in connection would be cool. This has a cord that plugs into standard USB port. Sure, it’s weird, but it works. The battery life is so long, this is hardly a concern. Plus, mine came with an extension usb. So fine. It all tucks away neatly with the usb transmitter in the keyboard behind a removable door. It’s fine. Guys this keyboard is 25 bucks. The backlighting is good, it is backlit. There must have been some mix up with models at some point. ** This works with my Xbox and my Nintendo switch. It just works. No hassle, plug it in and it works. Range is fine for a standard living room. What is there not to like. *** haven’t used the touchpad. All touchpads suck. It’s a cheap rechargeable, portable, light up keyboard with a good battery life and nice form factor. Just buy it ... show more

    • Recommend? Yes. Cheap and glitchy? Yup, That too.
Style: 2.4G Version
Before I start, WARNING: Some of the negative reviews given to these keyboards are well deserved. If you want a really good keyboard that will stand up to heavy use and abuse, you might want to pay up to five times more, and get another brand. This keyboard does have it's uses though. Despite the negative things I'm about to say about this keyboard, I would purchase another for the light duty applications I task it with. Overall, it's inexpensive and it works (for me). The reason I will stress the negatives in my descriptions below, is I want YOU to make an informed decision. Please keep in mind while reading, that my Brother and friends that I have purchased this keyboard for still own theirs and have not replaced it with a different brand. Even those who's keyboards err... didn't meet the stress test, asked for a replacement and not another brand. That said, please read on. I own several of these keyboards, have purchased them for others, and may purchase another. Likes: Price, price and features. (yeah, I said price twice.) Dislikes: No manufacturing quality control. Some of the keyboards that I own have their own "Character" new out of the box. Some have a tactile "click" when you press a mouse button, Some don't. Press and hold mousepad buttons on some don't work at all (although there is a "work around" button in the upper left hand corner for drag and drop issues.). The right mousepad button on some don't "Press" (although tapping the right button WILL bring up your menus) Sometimes I have to adjust the position of the keyboard to get a better "line of sight" to the computer. If this sounds pretty bad, that's because it is. I have to point out though, that not all of the keyboards I have received have these faults. Just be aware, that there is a percentage that I have received that do. The down side is you never know until it arrives. 1. If you are a gamer, this is NOT the keyboard for you. 2. If you are a typist, work moving a lot of files, or are a heavy keyboard user, this is NOT the keyboard for you. 3. If you are a business owner looking for wireless keyboards for your workers across a network, This is NOT the keyboard for you. Now, the question is, with all that negative stuff, why would I continue to use them and buy more? The answer is, that even though there are are negative issues with some of the keyboards I have received, they are inexpensive and work decently for MY applications. The back Story: I have a mini computer attached to each of the four TVs in the house that I use for streaming both over the LAN and the WAN. (That means I have a local media server where I store the movies and shows that I DVR until I have watched them as well as paid subscriptions to Netflix, Paramount Plus, Peacock and Hulu) Mostly I like these computers, because I can transfer files, and stream across the LAN to any room in the house (with a TV), and because even the newest TVs don't seem to offer onboard apps to ALL of my paid streaming services (and even some free ones). I also like watching Thursday night football on amazon prime Video. (They're great for older TV's also) I have a Rii wireless backlit keyboard (with mousepad) attached to each computer, to access media content through those computers to the TV's. I do use them sometimes for some work across the network, and to access to the internet without having to get up and go into the "office" to use the "main computer". The Good: In spite of some complaints, the batteries on the keyboards that I have purchased seem to last. Although I usually turn the keypads off when I finish with them, the timeout is short and reliable if I forget. I have left them on for days without using them, and have them light right back up and work when I press a key. I like the backlight in low light situations, and it pops back on after timeout by pressing the "light button" at the bottom of the keypad. The USB cable is attached, so I don't have to go searching for one when it's time to charge the keyboard. They are very cheap, and (once I get used to some minor character faults) work well for the little I ask of them. I have only managed to trash one myself (by sitting on it). My brother trashed one by rolling on top of it in his in bed. A friend trashed theirs (it looked to me) by dropping it from a height and having it land on a corner. I, my brother and the friend were happy with the inexpensive (Cheaply made) keyboards and just went for a replacement instead of another (more well made but very expensive) brand. Overall: Cheaply made? Yes. Made for (even slightly) heavy duty? No Will it survive abuse? No Do ALL of them have faults? No Do they work for my friends and I? Yes Would I buy another one based on the application I need it for? yes I hope this review helped you make a decision (for or against) whether or not to purchase this keyboard. In the end, YOU have to make the decision on what's right both for both you and the application you're using it for. Hey! This is Amazon. If you DO decide to make this purchase and it's defective, send it back and order another. Who knows? "Good luck Mr. Phelps". ... show more

    • Three years and still GREAT!
Style: 2.4G Version
I got this in Dec 2022 and use it almost everyday in my HTPC lounge. Three years for the price is great! It is connected via the 2.4G connector to my Win 11 PC and it has always worked flawlessly. The batt life is about 4 weeks plus and it fully charges overnight. I really like the backlighting on the KB and the way the keys are spaced, and I like the way the trackpad works. The only thing I don't like is I can't turn off the "tap" control, but that is a Win problem as much as it is with the trackpad. Sometimes it is too sensitive to the touch. At any rate, I would buy this again without hesitation. A really well designed and useful piece of tech. ... show more

    • key spacing too small, do not buy
i got it this morning, and started touch typing. shoot, i'm hitting all sorts of keys. i wanted to get a portable, folding keyboard that felt exactly like a desktop one. this did not. so i measured the key spacing. let me explain my measuring. look at the J and H keys on your keyboard. when i measured the distance between keys in the same row, i found the distance from the right side of the J key, to the right side of the H key. for the distance between rows, i measured bottom side of J key to bottom side of the U key. these distances should be the same for any A-Z keys (and they were, there was no quality control issue here). all 3 of my 15" laptops and desktop keyboards have 12/16" between keys in all directions. 12/16" edge to edge between adjacent keys, and 12/15" from bottom to bottom of keys. Then i measured a bluetooth non foldable keyabord, an amazon basics one. i could type full speed on it and it was fine. it's spacing was 11/16" edge to edge. yes this one was not full sized, but i seem to be able to type on it just fine 95% of the time. so this rii keyboard? 10/16" edge to edge left to left, and 8/16" from bottom to bottom. no wonder i can't type on this thing, it's nowhere near a regular spaced keyboard. the fact that NONE of the paid reviews pointed this out, makes me realize how worthless they are. look, it's a great design and form factor. it needs to be bigger so they keys are properly spaced, but the feel the build quality, the magnetic clasp, all really cool. it's just useless because my typing accuracy will be s***. im going to be more accurate typing on my tablet screen with two thumbs. the non letter keys, the punctuation marks, are even more squished, and likely going to be even harder to hit while touch typing. the full keyspace on the almost full sized amazon basics bluetooth keyboard is almost 10". the full keyboard on my 15" dell laptop is 11.25" and 12" if you include the pg down and pg up keys. i will be returning this as soon as i can. if they just made this will full sized key spacing, it would be PERFECT. ... show more

Style: 2.4G Version
I bought this keyboard 11 months ago and it stopped working. I read it had a 1-year warranty and I said to myself aw man, they will never respond or replace this defective unit. Well, I was wrong, very wrong. They responded in 12 hours and sent me a new board right away. No fuss, hassle, or anything and they didn't require me to send the defective unit back which would have cost at least $10. Also, the replacement board is better than the first one as the battery lasts 5 times longer before needing charging. Also, they made the letters and numbers much easier to see without having to use the backlight, so I can see the characters with just the room light or daylight. I would recommend this unit and seller to all my friends. Great customer support!! ... show more

    • Almost...
Style: 2.4G Version
I've tried a whole bunch of wireless lighted keyboards with a touchpad and this one rates as Almost. This keyboard is the only one that has sorta worked. The lighting is almost readable in a dark environment and yes, I have tried all the colors and they change if you hit the key inadvertently. I have the wireless version and it has an effective range of less than 20'. Sometimes if you turn the keyboard to vertical, making it imposable to type anything, the cursor might actually work properly. Touch pad works when it feels like it. It goes into mag mode at random. The battery life is decent but it doesn't stay on very long whether plugged in or on battery. Frustrating, it would be nice if the backlight time would be adjustable or stay on if plugged in. Sometimes, randomly, the cursor stops working and the dongle must be unplugged and reset. The charging dongle hanging out of the keyboard is annoyingly unnecessary, it can be stored but it's a pain to put it back into the keyboard after charging, the access cover is not captive so it's easily misplaced or worse broken. I don't see any advantage to a captive charging umbilical cable that is so short it won't reach the charger or directly plugged into the computer. If the cable fails the keyboard is junk, if it had a separate cable, a replacement cable could solve the problem. The best thing I can say is this is the best functioning of ALL of the keyboards I've tried with similar specs and believe me, I've tried ALL of the other keyboards with similar specs here on Amazon. I try others and come back to this one because the others don't work, fail within weeks or don't work as well. Unfortunate. That said, a LOT of improvement could be had for this keyboard. Well it is relatively cheep so I guess you do get what you pay for in this case. ... show more
