Ordered several of these over the past years. They’re are some of the few Bluetooth dongles that work great on older Apple Macs (Mac OSX 10.4 / 10.5 etc.). The other brands or the BT 5.0 version aren’t recognized by the system but this one works flawless for headsets , keyboards etc.

日本メーカーの Bluetooth 5.4 のアダプターでは接続が非常に不安定でしたが、この TP-Link のアダプターは今のところ問題なく使えています。 キーボードやマウスを接続する場合、Bluetooth 4.0 で十分だし、Qualcomm 製チップセットを搭載しているところが決め手でした。 あと、地味ですが、アダプターに Bluetooth のロゴが刻印されているのもよいです。他の2.4GHz アダプターとの区別がつくので。

It's as easy as ramming it in a USB port and all Bluetooth functionality unlocks for you to use immediately. Windows 10 acts like you have Bluetooth built in and you can start syncing with your devices straight away. The range was much better than expected and speed is just as good, if not better than my laptop's Bluetooth. Highly recommend to anybody running Windows 10. It should work with Windows 8 & Windows 8.1 too, but I've only tested on Windows 10. Many people have trouble with other Bluetooth adapters not working and most recommend this TP-Link BT 4.0. Compatible with the latest standards of Bluetooth and backwards compatible with all previous versions so you can use any Bluetooth device to it's maximum potential with minimal energy consumption.
