Review on COO LED Slim Dual Mode Wireless Mouse (Bluetooth 5.1/2.4G) – Rechargeable LED Mouse with 3 Adjustable DPI for iPad OS 13, MacBook, Laptop, Mac OS 10.10 by Jose Isaacs

first let me be clear that my operating system is windows 10 pro. Impressions: 1. When you open the box, you will think there is no USB; it's not, it's just inside the battery compartment.2. This is automatically installed in Windows 10 Pro. I suspect it's the same for all other OP compatible systems, but your mileage may vary.3. Functions: left and right click, trackball (works on Windows 10 Pro, may not work on older systems like XP), swipe forward and backward, and DPI.4 adjustment knob. DPI is set to ultra-sensitive by default, so you'll probably want to tweak it. Once set it was very smooth and responsive. Overall, it costs less than $7 and works flawlessly; what else do you want or need? I will come back and change my review if I run into any issues but for now all in all this is a 5 star product and I totally recommend it! Hooray!
