Pairing is easy, the magnet is nice and strong and the sound is fine. But there are a couple of issues:
1. The connection is simply not good enough. There is less than 3 meters of direct line of sight with no obstacles between my laptop and the antenna, and yet is still drops out for half a second pretty often.
2. Sometimes there is a random bug where you can't connect to it, and you have to turn the device off and on again to fix it, or even outright uninstall it from your paired devices and pair it again.
If you really care about a good listening experience or need this for any sort of semi-serious purposes, then you should avoid it and pay a little more for a better and more expensive BT receiver.
If you just need a BT receiver for casual home use and need it ASAP, then sure go ahead, but it will most likely be a temporary buy until you get tired of the dropouts and want a properly working receiver.
