Serious weaknesses

Unfortunately, the display for one revolution needed not a minute or 40 seconds (like my Vorbewerter thinks) what I would find great, but is about twice as spacious, which I think is a shame, because then you can not see the model so alone. Even the body is silver, as the picture at Amazon suggests but black. Unfortunately, you can not change the direction of rotation, and the display makes the quieter grinding noises.

Two days later: After use commercially fresh Ansmann batteries I have to say, unfortunately, that the slow speed now no longer works and make faster after only 30 minutes, the batteries limp. Become why send the item back. Unfortunately unusable.
