quite good and strong. in the first 20 hours of use, the clip that connects the dust filter to the sander broke

For the price, it is very good. As a point of comparison, I have the BOSCH PSM 80 A, which I mainly use. I bought the Skil 7261 AA because of the attachments it has. I work with the triangular-shaped one. So, I will judge the Skil 7261 AA based on how it works with this specific extension. Compared to the BOSCH PSM 80 A, it makes more noise and transfers more vibrations. It is powerful and does a very good job with the triangular-shaped extension. It performed very well on blinds. Convenient to hold. Spare parts for both the triangular extension and if someone wants to use it as a delta-type orbital sander are available from a well-known competitor manufacturer. I didn't have any trouble finding them.

Very powerful machine and sturdy construction. The additional attachments are very useful, but what stands out especially is the one for the blinds on the shutters

A tool mainly for amateur use. It can reach places that most sanders cannot due to its many attachments. Obviously, it doesn't do as good of a job as a sander that only does one thing. Sandpaper in the shapes it has is not easily found, but you can get regular sandpaper by the meter and cut it into the shape you want.
