The stick is built minimalist: the board is in the red slider, the front end at the same time also forms the guide for the USB port. The familiar metal guide which surrounds the contacts with almost all USB devices, there is not so here. This is handy, because the contacts are better protected when retracted from dust and damage than all other sticks with sliding mechanism. That was the reason to buy for me, even if it leads in principle, that the stick a little shaky sitting in the computer (in practice no problem). *
Unfortunately, you can spoil even this brilliantly simple design: The slider has the black case pretty much match what indeed is not a real problem, but acts just somehow unsound. Important: The stick snapped in the extended state is not strong enough, so that sometimes the board pressed into the housing instead of in the connection when connecting back.
Conclusion: With its simple and thoughtful design Stick is probably virtually indestructible. Unfortunately, the poor performance tarnishes the image and the processing is unsatisfactory.
* Update: Yes, that's a problem with the wobble. From the USB port of my tablets the thing slips out, and after a few months he keeps using perhaps through fatigue in my USB hub of Hama is no longer correct. Review therefore lowered to 1 star.
