Review on Wireless Gaming Keyboard Mouse Combo: Backlit, Rechargeable, 2.4G, Soundless, USB, for Home Office Game Windows/Mac (Black) by James Brault

The mouse is too sensitive. The pointer jumps randomly. Sometimes you don't even have to touch it to make it bounce around the screen. (Update: I bought a mouse pad and moved my tower to improve connectivity.) The connection radius is extremely small and it becomes unresponsive when you get between the receiver, mouse and keyboard. This is sold as a gaming keyboard and mouse, but anyone who plays PC games knows you need to use both at the same time to play games. This mouse and keyboard cannot be used at the same time. (Update: The mouse and keyboard were in the wrong position relative to the base, and when I got between line of sight and devices, they didn't receive a signal and had to be woken up) If you press a button while using the mouse, the mouse goes goes into hibernation and you cannot play games. Just one color to highlight. Right now I only need the light to see the keys at night and I'm trying not to be overbearing. I don't know why only one color. These are LEDs, they must be any color. Otherwise, the key movement is nice. Quiet mouse is good. Batteries hold a charge well. Loads fast. The keys are interchangeable.
