We have an old house with old doors and door frames, which can use a coat of paint. Accordingly, the old paint must be sanded down and the doors in front of the new paint. We have us worried this multi grinder because it is perfect with the slightly larger grinding disk to grind larger, flat surfaces and can grind the smaller areas with the pointed triangular plate. Our door frames consist partly of five consecutively located densely groove - that the "Fitzelarbeit" is, as you can surely imagine. With the grinder from Bosch but I can edit the grooves quite well due to the triangular tip. A continuous control allows me to define exactly how high should the intensity. At the same time I can influence on the machine the grinding result continue with the pressure. Thus, the operation is not necessarily really easy craft savvy woman for me. The sandpaper is simply glued on it and can be removed after the wear and easy. I now for two weekends working with the multi-sander and am very satisfied. I can also the other reviewers do not connect when it says that the device is too heavy in his hand in the long term. Even after 6-7 hours grinding the arms was not dropped. A negative point is maybe the dust collector, the course does not catch everything. However, it is to connect a vacuum cleaner that way. I have not done since I saw no need for it with a mask with open windows and doors. That is why this point is currently playing for my overall not matter.
