Quality Find
I've had these for a month now and I'm still very glad for it. This is a great value for the money, everything works great right out of the box, it looks fun, and it's go me having a good time gaming.

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!

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.

Keyboard replacement for PC
It's worth the price, it's easy to use, it works quite well, it has a simple yet nice appearance when the light is on, it's durability is approximately 2.6 years even if a child tossed the keyboard like an American football it works well, its size is the same as any keyboard of that many keys, however it's a little bit heavier than other keyboards of that size.

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.

Very Bad Quality
It's just really bad quality... after only ~3 months, the scroll wheel broke, the paint is chipping away from the keyboard, and the buttons break on the keyboard.

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.
