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.

So far, I have used it to sand the bed frames and it did a great job. It is easy to use with one hand, although the vibration it causes numbs my palm and gives the feeling of an unstable grip, but for the first use it didn't cause me any problem.
The negative thing I find is that the package includes only one sandpaper grit, which doesn't help in the complete processing of a material (e.g. furniture), and during my online search for sandpaper replacements in different grits, I have found only 1 product from another company.
It produces loud noise (91db), but it is at a relatively tolerable level.
The sandpaper has good and stable application on the sander as well as on its accessories.
The accessories included in the package are very helpful, especially the one for concave surfaces.
I find the dust collector with a filter excellent (minimal to no dust presence during outdoor use) as well as the ability to attach a vacuum cleaner.
Despite the limited use I have made of it, it seems to be a good tool that definitely worth its money.
