Since I have had very good experience with a lawn mower from this manufacturer and the device is considerably cheaper than the common brands (eg Bosch or Metabo), I decided to buy, especially since it was only used for one-time use kurzfrsitigen. The sander was delivered with a piece of sandpaper (medium grain). But since I needed coarser and finer sandpaper for sharpening, I wanted to buy more, the lack of sandpaper at the hardware store. The sandpaper must have a suitable hole, so can be sucked out with a connectable storage Sager of swarf. The common brands have agreed on a unified solution, only Einhell travels as a special rail.

Unfortunately, the successor has the same problem with the sandpaper.
