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.
Review: Long range Bluetooth and works great - Setting up the device is straightforward. Just follow the instructions in the user manual — make sure to uninstall any old drivers first — then install the new drivers. After that, simply plug the Bluetooth adapter into your laptop’s USB port and connect your device. The signal strength is excellent. It covers a long distance, and I can use Bluetooth throughout my entire house without any issues. I also really like the compact size and the foldable, removable antenna. Overall, it works great and does exactly what I need it to.

### ⭐⭐⭐⭐⭐ Plug & play, Long range. Works great!
*by M***L on March 5, 2026*

This bluetooth adapter is just what I needed. My new computer has bluetooth, but for some reason the range is only about 3 feet. I needed something that would go at least 50'. This works perfectly! Just plugged it in, and Windows 11 recognized it. I am now able to walk around the office again while still listening to music on my airpods connected to my desktop computer. Definitely would buy again when/if needed.
