DO NOT BUY THIS PRODUCT. I've been using the adapter for about 2 months and it has worked great. It felt noticeably thin and warped, but that didn't bother me at first. After I was done with that, I put the included end cap back on the adapter and left it in my desk drawer. After 2 weeks I decided to use it again but when I plugged it in the LED didn't light up and it didn't show up in Device Manager. Also, the sync button on the bottom broke after a few uses and now dangles uselessly when the adapter is moved. I've tried several fixes, but the only online guides are dedicated to troubleshooting when switching from Windows 7 to Windows 10.
