Review on 🖱️ TECKNET 2.4G Wireless Mouse with USB Nano Receiver - 18 Month Battery Life, 3 Adjustable DPI Levels (Grey) by Billy Mariner

Same size as a regular wired mouse. Single AA battery design has much better battery life than AAA mice. The sleek plastic body makes it feel very light, so it's not the highest build quality, although it has survived a few falls unscathed so far. It doesn't have the typical red LED on the bottom but uses invisible infrared light.
