The technical data are good, the stick is actually quick and not too expensive. In the photos here he comes, however, gone a little too well. The processing is not convincing, he is very light, yet also built cheap, thin plastic, creaks to the touch, USB plug wobbles in the embroidery. On the back is an adhesive strip that you can plan better.
One could get the idea that the purple strip is illuminated during operation, which he is not, however, instead of a blue LED in the middle of the stick by the black transparent plastic lights.
UPDATE: The stick went after a few months (internal) broken, I had to send him back to Amazon (the problems refunded the money).
