It does its job for a single room.
-it's not for professional use, it gets hot.
-the power switch does not stay ON, it turns off at the slightest touch. So you have to keep your finger on the spot all the time, which makes it tiring.
-it doesn't have a case and the cardboard packaging will wear out over time. After that, it will probably be loose.

Very nice tool although sometimes the head in front bounces, however the vacuum that is built-in is convenient because it doesn't lift much dust

I don't have much of an opinion on these tools. I bought it and used it to sand the floor at my family's house on the island. It was about 60 square meters and I initially sanded it with a 40-grit, then 80, and finally 120. It turned out really well. I also attached a couple of 5-kilo dumbbells to it and it sanded almost by itself. Of course, it produced a lot of dust because I didn't have a suitable vacuum (I broke a regular household one that I had), but I also came up with a solution there using a blower/vacuum and blowing the dust out of the window (fortunately, there are no neighbors nearby).

Honest and affordable sander with a rotating head that performed very well in sanding walls. As for spatula-like surfaces, it requires medium speeds, special attention, gentle work, and 220 sandpaper to avoid marking the stock and causing damage. However, this also happens with much more expensive sanders. Still, it is a good choice and user-friendly.
