## Customer Reviews

### ⭐⭐⭐⭐⭐ This version Of the K20 Red Thunder almost got me to where I wanted it.
*by S***B on December 14, 2024*

3 Cons: 1): Only the Red color can be made constant (FN+5). I don't like colors changing dimming on and off. Personally I like the Teal color but couldn't get it to stick.2): The mouse had better color control. I like the fit and mouse control BUT, when it goes to sleep it won't wake up UNLESS YOU BANG IT ON THE DESK TOP. So, I'm back to my OLD PITA Microsoft mouse with the long receiver.3): Thought I could charge the both at the same time using my older K20 cable BUT, the power cords are different. Mixed them up unknowing the situation so after straitening them out I had to put labels on them.Having fun and seeing RED. Hate my opinion I like Red Thunder.UPDATE 01-08-2025: Figured out my AutoScrolling Color problem. Everything is AOK with this keyboard.Answer is not in the instructions pamphlet. FN + 5 doesn't do just 1 color = RED. By accident I found that it can select all the colors buy holding down on the FN key and continue to scroll to the color U want to have ON all of the time by pressing the 5 key over and over. It's a wonderful ting.

### ⭐⭐⭐⭐⭐ The plug in is in the MOUSE!!
*by S***  on January 13, 2025*

I love wireless wireless key boards, and know how to install one. There were NO instructions and as I do not use a mouse, looked for the plug in on the back of the keyboard where they usually are...not there. Read the instructions, charged overnight, then tried again with the only thing I could find, the plug in charger. SENT THAT KEYBOARD ONE BACK AND ORDERED ANOTHER ONE. When it came, same issue. Finally a friend looked at the bottom of the mouse, there was the plug in.Jeez.....just tell folks where to find it for Pete's sake!!Otherwise, great keyboard.

### ⭐ Worked for a bit, updated review
*by J***R on April 28, 2023*

I purchased it and just received it. I found out pretty quick that I needed to charge them right away and that wasn't my favorite on top of not having any kind of user manual in the box or on the outside. I was pleasantly surprised to find that they share the same receiver, more usb ports for me to use. The matt texture on the keyboard isn't my favorite either but I imagine with a light cleaning and some use it'll wear off. The colors worked as soon as I finished charging.Word of caution: The mouse will not work while charging, but the keyboard will.------------------------------------------------------------------8-26-23Update: I change my earlier observations on this product and rating from the few months that I have had the keyboard and mouse, and I currently do not recommend this product as a gamer. I find the product extremely frustrating.Keyboard: About every 4 days I have to restart my PC to reset the keyboard's functionality. The keys become scrambled in every way. E becomes the windows hotkey, 3 becomes my spacebar, enter becomes my hotkey for my heals and esc does absolutely nothing half the time when it hasn't reassigned itself to a different key on the malfunctioning occurrence. Half the time the keyboard does not register my keystrokes when communicating with my raids, and it looks like I don't know how to spell anything. Turning it on and off again doesn't work at all for this, neither does pulling the USB out from the PC.Mouse: The mouse is somewhat functional, except for the fact that you have the 45% chance of clicking something on a page and it acts as if you hit the back button even if your cursor is nowhere near it. Or that none of my keybinds will stay where I set them. Then there's the constant DPI reset for absolutely no reason, making me reset it the speed I am comfortable at. Again, turning it on or off again does not fix the issue.For the price it advertises, it does the job for anyone looking for a cheap fix. But if you're looking for something functional and for decent gaming I do not recommend this set. Find something else.
