Review on 🖱️ TECKNET 2.4G Wireless Mouse: Ultra-Long Battery Life, 3 DPI Levels, USB Nano Receiver - Ideal for Notebook, PC, Laptop, and Computer (Blue) by Marco Carpenter

After putting a USB stick in a laptop and putting a battery in this mouse (only one is needed), after the PC finally recognized it, it worked Mouse about two minutes. After that he fell asleep and even when I moved him he didn't wake up. Reseating the key didn't work, nor did reseating the battery (which was brand new). Luckily, in the same order as this mouse, I bought another one from a major manufacturer. I switched the battery to this one and after adding the correct second battery I've been using it ever since. There is "cheap" and there is "cheap". This mouse is a cheap POS. Buyer Warning.
