Review on 🔌 Avantree DG40S USB Bluetooth Adapter for PC - Bluetooth Dongle for Desktop Laptop, Supports Mouse, Keyboard, Headphones, Stereo Music, Skype Calls - Compatible with Windows 10, 8.1, 8, 7, XP, Vista by Chris Meers

Terrible purchase, unfortunately. You get what you pay for I guess. The adapter doesn't like being switched between computers. I usually take it from home to work and back, but sometimes the adapter doesn't like working at work or home when it's on, even after a computer restart. Also, the Bluetooth adapter doesn't actually work with the Logitech Bluetooth keyboard I recently bought (NOT A UNINGERING RECEIVER, I'M SURE) so I'll have to buy another one now to see if it works with this one. Thankfully it works with that other thin keyboard, but it's still annoying that for some reason Windows doesn't recognize it every time. Edit for verification: The seller tried to correct my 2 star rating by letting me know they had a defective batch and sent me a new one. I was fine with a working Bluetooth device. Unfortunately, instead of sending me a bluetooth device which is a GENERAL bluetooth device (connects to all bluetooth devices) they sent me an audio ONLY device and in fact windows didn't even recognize it as a bluetooth device to turn it on or off. If a user buys a GENERIC Bluetooth device and has problems with that device, why not replace it with SIMPLY THE SAME OR BETTER DEVICE? Lowering my rating to 1 star and will never buy from these people again. Buy this instead, USB Bluetooth Adapter for PC, Zexmte Bluetooth 4.0 USB Adapter Wireless Dongle Compatible with Desktop PC and Windows 10 8.1 8 7 Vista XP Computer, Works Much Better Than This (Less Signal Dropouts/Dongle- Repeat for keyboard etc.), but I would recommend using anything that is a Logitech Unifying Receiver product if possible.
