    • Rii, first impressions.
So far, so good. I plugged it in and it worked with all the lights as shown on the packaging being visible. Keys are still stiff but it will take a while to settle in. The mouse is comfortable and is taking less to get used to than I first worried it would. For the price and lack of hassle this was a decent purchase. I won't be gaming on it but like having the lighted keys as my eyesight isn't what it used to be and now I don't have to worry so much about typos. Not quite as wide as my old keyboard but this may be a blessing as there will be more room for a cup of coffee on my desk. ... show more

    • Solid setup and Great price
RII consistenly has made great products. This lil keyboard and mouse combo was well priced, and feels like a solid RGB combo. The mouse feels nice in your hand and responds really well and the keyboard has zero lag and the alternating colors are hypnotic.

    • Not bad for the price
This is my first time ever using a keyboard and mouse for gaming so I might not be very well experienced, but for 20 bucks this certainly feels like a decent set of equipment. I've been using it for a few days now and I gatta say I'm loving it. The keys aren't all that loud and has a decent response time, perfect for late night gaming without waking anybody. The mouse feels just as responsive and the lights and colors in both items are just bright enough to match my led lights in my room. The only problem I have is with the mouse really. It has a DPI button so that I can change sensitivity on the fly, that part is cool but the problem I have is that whenever I hold press on both the left and right front buttons along with clicking the back side button, it changes the DPI. it's really annoying and throws me off my game. Not sure how something like that even exists if there's already a designated button for the action. I'll assume it's a defect for now but other than that I'm quite satisfied with the product. However is will not be buying another if the above issue is not fixed. Thank you. ... show more

    • Worked from 6/8/24 to 4/4/25 *seller didn't reply but company's warranty support did!
For $14.24 (as the promo price is currently) you can't beat getting a backlit combo keyboard + mouse for this price point. I don't game, so I can't speak to that. However, for office work (memos, spreadsheets, computer programming, etc.) this is a comfortable and sturdy combo device to use. *QUALITY UPDATE- I purchased this item on 6/8/24, and as of 4/4/25 (roughly 10 months), the keyboard had an assortment of non-working keys. The keyboard sustained no liquid spills or no impact damage to it. From my review above: I use the keyboard for office work. On 4/4, I messaged the seller about my keyboard malfunction and I never heard back after 3 days. On 4/7, I tried one last resort which actually paid off! I had kept the Rii keyboard box in my storage unit and inside the box was the User's Manual which had an email address for customer service in China. I emailed customer service, gave them the serial number and all the details on the box and explained the malfunctioned keyboard. On 4/8, customer service emailed me back with a shipping tracking number and informed me that they sent out a new keyboard and mouse unit to replace my keyboard. What a great deal! **P.S. for everyone--make sure you keep your box and User's Manual in your storage OR cut out the serial info off the box and keep the User's Manual somewhere handy! ... show more

    • Very nice keyboard
The keyboard feels good like any other keyboard so don’t worry about quality and the mouse does feel a little cheap but only on minor details like materials. They both work great and preform very well! I would very much like to see more light modes because the keyboard only has 2 and the mouse just blinks faster the more you change the rgb light pattern. ... show more

    • Cheap, miss leading, but, works.
This products title is a bit miss leading since it states the keyboard is a rii rk400 "rgb" keyboard which is later followed by led backlit so be warned now this is not a proper RGB keyboard as the listing may initially lead you to believe. However the mouse is RGB just not customizable, it changes colors in a breathing set up and for once it's not rainbow puke which is nice to see. Over all I bought this keyboard and mouse because I wanted a super lightweight keyboard for a media PC I built to be used from a couch or bed, places where using my high end keyboard was irritating to move around or have resting on your lap due to high ends having more weight to them. Cheap keyboards are usually extremely lightweight in comparison to a more expensive keyboard ie corsairs k70, so, all in all for my use this keyboard wasn't a bad purchase. So far all the keys feel okay they are smooth and rather responsive, however high end keyboards will always have the better keystroke feel. The mouse feels cheap however it has a decent shape to fit my hands nicely. The clicks are light and feel great, the switchs feel similar to what Corsair mouses use which are omron switches, if I'm remembering correctly, not the exact same feeling but pretty close. Over all this wouldn't be a bad set up if you're working on a budget. Things I wish they could improve on is adding full RGB, because in 2021 RGB light strips are similarly priced to colored led strips and at this price, a customizeable RGB backlight would definitely up my rating by a large margin and put this keyboard ahead of all the other combos at the $15 price point. ... show more

    • Great keyboard and mouse set.
Very happy with the keyboard. The way the keys feel and the typing just flows smoothly. The lights are a nice look and helps to see the keys.
