I am using it. It works fantastically. Infinite faster than the one I had in the beginning, when I started my zigbee network (a C2531 based dongle) and much faster than the one I've been using until I got this product (I was using one from AliExpress, with the same processor). Strongly recommend it. If additional information needed, let me know. I will be more than happy to answer. BTW, besides the product itself, man, they have an outstanding customer support in case you need it. (https://www.facebook.com/groups/HomeAssistant/posts/3361394887465191)
