Nice product and pairs quickly and easily with my dell xps. Haven’t used it extensively yet.
Shipping was fast (as fast as China-US shipping can be these days) and the numpad pairs reliably with my PC. The antenna seems to be really weak, though. My PC is mounted on the wall above my desk and even just 1 meter away the pairing is unreliable. Farther away, it works again. At 3 meters it quits. Works well for my laptop, though.
