Review on 🖱️ Corsair Katar Pro Wireless Gaming Mouse - Lightweight FPS/MOBA Mouse with Slipstream Technology, Compact Symmetric Shape, 10,000 DPI - Black by Lynn Cole

I bought this mouse for the feature set, which isn't bad at all - AA battery power, a decent sensor, and Bluetooth and USB wireless connectivity. It all adds up to a pretty decent mouse. My biggest concern, however, is the power saving feature of this mouse. After a short time (probably 30 seconds to a minute, I didn't measure the time) the mouse goes into a deep sleep state from which it takes 1-2 seconds to wake up. This leads to constant frustration as you constantly have to wait for the mouse to wake up before you can use it again. While it may seem insignificant, the constant dreams add up, turning a simple mouse movement into a frustrating experience.
