Review on Techkey USB Bluetooth 4.0 Adapter Dongle: Enhanced Connectivity for PC Laptop Desktop, Stereo Music, Skype Calls, Keyboard, Mouse | Windows 10 8.1 8 7 XP Vista Compatible by Alex Jones

Hardware is good. Software wise, the drivers kill it, making it one of the most frustrating keys I've ever used. No computer will recognize this right away, you either have to go to the website or use the CD to download these weird drivers called CSR Harmony Stack. This is by far one of the worst drivers I've used in my life. If you disconnect and reconnect your bluetooth dongle, either on purpose or accidentally when you accidentally bump into it, the software will crash and stop working UNTIL YOU COMPLETELY REMOVE AND REINSTALL IT. Sometimes it refuses to work even then, sometimes it will work but the sound quality will be awful, like it's underwater. this. I don't know what causes what. I unplugged the key as I needed room for the USB drive to transfer files, transfer the files and plugged it back in. It didn't work and I didn't feel like uninstalling and reinstalling the driver for the fourth time. So I just connected the headphones with a cable. Literally two weeks later, the CSR software reappears and works by itself.? Why?! I didn't do anything, he just decided to go back to work on his own! Whoever developed this software didn't deserve the job. I've searched for alternative drivers but unfortunately couldn't find anything other than these CSR drivers. The ones they provide on the CD and on their website are just different versions of the CSR drivers and they both give me the same problems. While the hardware in the dongle may be fine, the fact that it's only compatible with these CSR drivers makes it a frustrating piece of junk that was so annoying I actually despise the thing. I do not understand it. The description states that Windows 10 will automatically install the necessary drivers. It is not. You must use the CSR drivers. Buy a plug-in that Windows can recognize immediately.
