Review on 🎮 Rechargeable Wireless Gaming Keyboard and Mouse Combo with Rainbow LED Backlit, Mechanical Feel, Ergonomic Design, Waterproof and Dustproof, 4000mAh Battery, Silent Mice, Compatible with Computer Mac Gamer – 7 Color Backlit by Eric Ross

The buttons are poorly lit and if you look down you can see excess paint on the frame. This cheap spring clip doesn't wear out at all. Mechanically, the keys don't feel as advertised. All product photos in this listing have been retouched to show brighter, more clearly lit keys. I assure you that this is misleading advertising. There are no keys (as shown in the photo in the listing) to control the speed of the color change on the keyboard - they simply don't exist. You can only toggle the keyboard backlight on and off. The mouse colors change but blink intermittently as if there is a short circuit, perhaps to simulate lightning? The keyboard stays on for about 30 seconds before turning off.
