Completely unacceptable, however, is that in my device after about 20 .. 30 seconds (!!!), the speed drops to almost completely Felt 180 U / min and when pressed again, the speed control is no longer also increases. And that with completely no-load running. If the device after a short running time already at the border? A certain temperature increase can be so, however, the built-in slip clutch or the engine already be overloaded?
I hope now that this effect is an isolated incident and due to a lack of equipment or manufacturing defect is and I get a fully functional replacement product to shipping the device to the manufacturer. The way from the manufacturer, I must now go unfortunately because I now already possess the goods almost 5 weeks. Today, however, was only the first use of equipment. After this experience, I would now like to return the device to Amazon and purchase canceled. Complete namely rather a systematic error because from the outside absolutely no shortage can be seen.
From a purchase, I can only advise therefore from today's perspective.
Update on 20/01/2014:
After contacting the company Beurer the unit was impeccably replaced with a new one. This is now in order and met my expectations. I correct my vote today, therefore, from one to three points. After another prolonged operation without malfunction is certainly yet another point possible.
