Review: Great keyboard if you dont want high name brand - Really nice budget keyboard. Rbg lighting. Yoh can download app to change the light pattern or do it from the keyboard directly. Good value gor the money. Been using for 2 years now. A key or two got stuck here and there but they give 5 extra so i replaced and all good. Cleaned it out and worked like new. Feel is great and clickiness is nice. Quick and responsive. The black matched my pc.
Review: Feels very durable and takes up little space. - BUY IT BUY IT BUY IT!!!! This is by far my favorite keyboard, I had a Razor keyboard with the number pad and it constantly got in the way when playing first person shooters. So I went with a smaller footprint and fell in love with the mechanical style. The keys are very responsive and not loud at all. I was looking at getting the smaller razor but it's $200 so decided to give this one a shot and it's well worth it.

### ⭐⭐⭐⭐ Looks great, most features work.
*by Y***0 on February 3, 2022*

Orginal review (3/22 Edit below orginal): Ultimately, I think I would have liked to exchange this board for another one. There wasn't any stock though, until the return period ended. There are a couple of feature shortcuts that don't work on my board, and I've experienced a few different characters that stick sometimes, and cause repeated characters in a document or typing field. I replaced the worst ones with extra switches that the board came with, and that does seem to have helped. I also requested additional replacement switches from Redragon, since I had to swap so many already. They said they would send me some as soon as they're available. It is a great looking board, and otherwise works great. All of the connection modes stay connected without any perceptible lag, and the volume scroll wheel works just like a mouse scroll wheel, and keeps up with however fast I scroll it. The backlighting looks great, and I get really good battery life. It lasted 5 weeks before I needed to charge it again. It's way more fun to type on than my old wireless keyboard, pictured, and it isn't even that much larger. The TKL version doesn't have separate M keys for the macros, they are secondary functions of the F1-F4 keys. When macros are set to the G keys, F1-F4, whichever is selected, will turn static white @ 100% brightness, and the G keys will light up green. Regardless of the color, mode, or brightness level the rest of the board is set to. I have included a of picture of this. I do like this board, it has everything I want and looks good doing it. So, it isn't perfect, and as far as everything wrong with my particular board goes, most of it wouldn't be a deal breaker worth returning it over. But, the repeating characters thing is worrisome. This is a keyboard, first and foremost, and I need it to work as such. If it starts doing that again, I will contact Redragon about a warranty replacement, and update my review. Update 3/22: I believe I have solved the issue with repeating characters. It is a Windows setting, not the switches causing it. In advanced power options, I disabled USB selective suspend, and this seems to have fixed it. I also set PCI Express Link State Power Management to off, and turned off hibernation and hybrid sleep. I haven't had an issue with my board working properly since, besides the feature shortcuts that didn't work out of the box. Raised rating from 3 stars to 4 stars.
