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. BTW, besides the product itself, man, they have an outstanding customer support in case you need it.
