It does almost nothing and due to the size of the machine, it can barely reach difficult spots and corners. The special small attachments for corners and curves constantly pop out of their special slots. Its speeds are more of a figure of speech than reality. The vibrations make the result wavy or nonexistent.

I bought it for 65€ on sale.
I was interested in the many accessories for specific areas.
It really helped me with my work, which involved 4 large blinds with grilles, on balcony doors.
There was a lot of instability on the surface due to old cracked varnish, from many years.
My observations.
The motor is powerful and did not heat up at all, after 3 hours of continuous use, only stopping to change sandpaper.
The dust absorption system works, but it cannot absorb all the material, which was quite a lot and I had to empty it frequently. I don't know if others collect more.
I would like it to make less noise, which at high speed was quite louder than others I have used and heard.
That's why I chose the low speed throughout the process.
Also, the vibration at high speed was quite noticeable, but I wouldn't say it was problematic.
The accessories helped in difficult areas, between the slats of the old classic blinds. That's why I chose it.
For amateur use and at this price, I would recommend it.
I wouldn't give any more than that.

Having 3 total sanders, 2 Dewalt and this one here, you immediately understand the quality of Dewalt. There is no comparison. I got it purely for the detailing attachments. Its vibrations are annoying (in my opinion). It makes a lot of noise. The automatic speed adjustment according to usage is laughable. This machine is a jack of all trades, but it doesn't do any of them perfectly.

It is not many abrasives but a little bit of everything. It does a good job and has the power it needs, but a multitool is not the same as a tool designed to do a specific job. It is convenient to have all the abrasives in one case, whether you take it with you or as an amateur you don't want it taking up space in the closet. It has a plethora of attachments for difficult areas and comes with plenty of sandpaper. The round sandpapers are the most popular on the market, but I haven't found the others elsewhere. For the small sandpapers, you can simply cut them from larger Velcro in the shape you want. The price is quite good for a branded sander, especially with so many capabilities.
