Disadvantages:
- In charger, the device is quite warm. In this state, the power is weakening very. Only when it has cooled, is back enough power.
- Housing can not be opened without destroying it. (I already have the second device because my first down has fallen while apparently slipped something inside. I could not see if there's something to judge. Although the engine still delivered full power, the device could no longer use, as it no longer ran around.
Needs improvement:
- Instead of a nickel-cadmium Akus should be in it for the price and a Li-ion Aku. (But I can not say anything after 5 months over the lifetime.)
- Instead of the little solid plastic housing, a metal housing would be appropriate.

Meanwhile, I have the third bar-Whip Supremo. The devices go with me reliably broken by one or two years. My newest device seems to have been improved. Thus the rotating shaft has a stabilizing black collar now. Let's see if the interior was also solid and make this device holds last longer than the previous one.
