Really excited to get this set for my laptop. I am on the road alot and get to set up in hotels playing on my laptop. needed something neat and smaller to fit in my laptop bag. After days of searching found this set. Love that the usb works for both keyboard and mouse. Love the lights on both, love that they seem to last forever. The ONLY problem I have is the mouse now is nearly unusable, I thought it would work itself out, but seems to have not. The wheel on the mouse doesn't work like it should, when scrolling it stutters really bad, when trying to game on diablo 4, with the scroll wheel you can zoom in and out, its impossible, it stutters, goes really fast, you scroll one way goes the opposite way. Really bummed about it, guess I am going to have to try another company's product. I have tried turning it off and on, unplugging the USB dongle, I've tried everything, just can't seem to get the scroll wheel to work. Other than that the mouse works, I just have been dealing with it, trying not to use the scroll options. I've tried to get help from amazon to no success. All I want is a mouse that works. Can't seem to get a refund or maybe a replacement, amazon makes it nearly impossible to contact support. So not sure what I am to do. *********** Edit: Since my review, the company has reached out and fixed my issue immediately. Sent me a new mouse and it's works flawlessly. I will be buying from them again, they didn't hesitate, they didn't complain, they offered to make it right and did so immediately. Very very very happy. Thank you!

If you're looking for a mechanical keyboard that won't break the bank but feels and looks premium, the RedThunder K84 is a gem. I bought it specifically for its 80% (TKL) design, which gives me so much more desk space for my mouse movements—and I don't regret it! The typing feel is incredibly tactile and satisfying. The switches respond instantly, making it perfect for both my long work sessions and late-night gaming. Plus, the RGB lighting is vibrant and easily customizable; it gives it that gamer edge without being overwhelming. My verdict: It's sturdy, comfortable, and has a build quality that easily competes with much more expensive keyboards. An undeniably smart and high-quality purchase!

Extremely disappointed with this. The keyboard was sluggish responding and would drop characters. After a few moments of us it would shut of completely - yes it was fully charged before beginning use. I contacted the manufacturer directly and they sent a second set - which had the exact same issue. Tested on multiple machines. The mouse was great, but the keyboard is unusable junk.

The Red Thunder K84 keyboard is seriously amazing! My son is a huge gamer and has gone through quite a few gaming keyboards over the years, but none of them even come close to this one. As soon as he got his hands on the Red Thunder K84, he immediately got rid of all his old keyboards — that’s how much he loves it! The build quality is incredible, the keys are super responsive, and the RGB lighting gives it that perfect, customizable gaming vibe. It’s not just about looks though — the performance is top-notch. Every keystroke is smooth and fast, making a huge difference during gameplay. It’s lightweight but still feels solid and durable, which is exactly what any serious gamer needs. If you’re looking for a gaming keyboard that delivers on both style and performance, the Red Thunder K84 is a total winner. My son couldn’t be happier, and honestly, I can see why — this keyboard is in a league of its own!

Genuinely surprised how great this set is. Works perfectly, great range. Fully adjustable keyboard RGB colors and modes - and both the keyboard and mouse are super lightweight.

So it feels not fair to talk about the build quality at this price range but i can’t help but point out that it doesn’t get much worse than this, the keys looked like it literally got spray painted so in the matter of weeks it would probably peel off if you use it heavily (i got it for my second PC to use it lightly but still), the lights look so cool but very terrible in functionality as in it just blinds you and doesn’t properly shine through the letters properly as its not single light per keycap which trust me it makes a big difference hence the cheapness, the mouse feet skates came in damaged and honestly the shape felt uncomfortable for me, I've owned many mouse shapes and i wanted to like this one but again looks cool but heavy for what it looks like and the weight balance is terribly heavy on the front end, overall weird feeling and also it’s not even flat like as soon as you hold the mouse firmly onto the table the front end suddenly lifts up ever so slightly but enough for me to feel it and gets me confused (the mouse skates not properly installed or the back and front are not sized correctly therefore the balance is off) honestly so sad for the waste of time and shipping boxes to just not even get to the part if the mouse is responsive or lags or not just straight up wrap it and send it back, so why the 2 stars not 1? I can see people getting this for the price especially as a combo if they don’t wanna do more research and they buying this for a kid (i wouldn’t even get it for my 10 year old nephew honestly it’s disrespectful) the 2 stars is more like 1 for the mouse and 1 for the keyboard.
