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.

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.

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!

Its a Great Product if you are just looking for a cheap keyboard n mouse to work or just use your computer. Its a membrane keyboard so don't expect to work perfect for games (buy a mechanical) N key rollover Max 6 recorded, Some ghosting of keys are evident in Gaming, the light pattern is fixed, only options are Static, Flashing or Off. Mouse feels light so Aiming might be a miss, again not a typical Gaming mouse. DPI settings works fine, sensor works great even without Mousepad but precision is lacking a bit. It has great character to it. Both Keyb n Mouse looks great on a Desk.

This is a great price for a great keyboard. The mouse works well too. The mouse does have a clicking sound (I ordered a mouse before that didn’t have any sound to it and I’m not sure if people prefer them that way…?) and the lights on the mouse and keyboard are bright and work great! The keyboard is pretty quiet which is nice. Definitely worth the price if you want to save money!

If you are needing a good keyboard to type with, this keyboard is the worst. It might be a great gaming keyboard, but using it to type is a bad decision. I type between 40-60 WPM depending on content, and with this, its just not possible. half the keys stick, and the placement is not consistent with standard working boards.

Honestly? Its fine. For the price it’s at and for how it looks, you could honestly do worse. However mine stopped working after about 7 months. I’m not rough on keyboards by any means and have never broken one. The issue came when it would randomly disconnect. The USB plug isn’t all that great and wears out quickly. The cable is also a bit flimsy. It was a decent placeholder until I made a decision for a permanent replacement.
