Mouse and keyboard wireless function worked fine, USB dongle plugged into Windows 10 laptop, connected with no problems. Mouse tracking wasn't as accurate as I'd like, but not terrible. Worked for about 2 weeks, but then the mouse wheel stopped working. The soldering on the board was so-so, with a couple of pins semi-soldered. I fixed them but the mouse still didn't work properly. As cheap as the set was, it wasn't worth spending any more time on. Just throw away and order the best combination of mouse and keyboard.
