Review: Goodbye to disconnections and fast file transfers via Bluetooth on my laptop - I bought the Techkey Mini Bluetooth 5.0 EDR mainly because I needed to transfer a lot of work documents from my phone to my laptop, and since I started using it, that task is much faster and more reliable. Although my laptop already had Bluetooth, the adapter improves it significantly: the signal is more stable, the headphones don’t disconnect, and the latency is minimal, perfect for music or gaming. The installation is super quick: you plug the adapter into a USB port, Windows recognizes it automatically (or asks to install a driver, although many are plug & play), you activate Bluetooth, and you’re good to go; you can pair a mouse, keyboard, headphones, and transfer files without any issues. I’ve been using it for several days, and the difference is noticeable: goodbye to dropouts, signal issues, and slow transfers. Plus, it’s so small that you hardly notice it’s connected, and the price is incredibly affordable for everything it offers. If you want a reliable connection, fast file transfer, and zero disconnections, this dongle is a purchase that’s worth every dollar.
Review: Easy to install, and so far works as described. - YOOOOOO! So i just got this delivered today. I have an older Corsair K63 Keyboard/lapboard combo that I wanted to start using. My dongle died for some reason and I could never get the keyboard to pair up via Bluetooth on any of my 3 rigs. BT built into motherboards plain suck. I disabled the install BT module on my mobo, installed this and it was instantly found. I'll be buying several more, for my other machines, as well as having spares, because this thing was cheap and a thing of beauty.

### ⭐⭐⭐⭐⭐ Works great for me
*by R***Z on January 31, 2026*

It was just plug and connect your device wanted to play a game with my controller but wireless. The controller didn’t have any lag on high end games like apex cod and siege. And for the price it’s pretty damn good. It has pretty good signal I can go downstairs and my AirPods will still be connected.
