Angle grinder operated by accu, usable. At full power the Accu is empty very quickly. Unfortunately, the Velcro sanding discs of this size are not available in normal stores. So always have to be ordered via the Internet.
I have not been able to try the device in the long-term test, but think that it will serve the purpose. The polishing machine makes a good impression and is also well made. The box is very handy and can still take a lot of additional discs
