Review on UGREEN Bluetooth Wireless Transmitter Keyboards by Michael Hudson

I tried to use it to replace my 3.0 because I think it didn't work well (already 5 years) and it doesn't work. All I use bluetooth for is a wireless headset and this thing can't even handle it. Edit 1: I originally gave this one 1 star, but I switched my PC driver from WDM to MME and now it works fine. Edit 2: The app they use to boot "Bluetooth" on this dongle stopped working and won't even boot on my PC now. That brings us back to a star! Hooray!
