Purchase on August 9, 2023.
We polished a whole car with precision and without much noise since the morning. It is tireless in terms of performance, although we used it casually, it will easily satisfy a professional as well, as it only stopped to change sandpaper every 6 hours.
The horizontal surfaces (hood, doors, roof, etc.) were a breeze to work on because it essentially polishes itself with just the weight. On vertical surfaces, the weight is noticeable as you get tired relatively quickly, but it balances out because you finish quickly with the power it has, so it's not a big issue, and if it's your job, you get used to it easily. Compared to an old orbital sander I had that would break all the time, you can say it's not silent, but at least it's tolerable... It makes half the noise of the old one.
As for adapting a vacuum cleaner to suck up the dust, you will need a fitting adapter from 30mm to 22mm. I don't know how easily you can find such an adapter, maybe someone who has done it can fill in.
Overall, it's a good purchase at €59. It seems like a quality and honest machine for its price. It doesn't look cheap at all!
Its durability over time remains to be seen...

Very powerful and sturdy sander. In terms of build quality and functionality, I would put it in the professional category. It is a bit noisy and relatively heavy. You can't easily operate it with one hand. Regardless, it offers great value for money.

I used it non-stop for 3 days, rubbing a kitchen with a total of 21 cabinets and 5 frames. It seemed extremely good to me. A little heavy for some high points that I wanted, but on the countertop it rubs on its own, it doesn't even require effort.

Very good and sturdy for its price.
- Attention!!! The nozzle from the sander is very small and requires an adapter (plug) to connect it to a vacuum cleaner to suck up dust when someone is working on a bench.

I used it on a new Swedish parquet floor with various sandpapers, it didn't work as well as a professional sander, but for what it is, it does a very good job, no complaints, also it didn't suffer any damage on doors or casings. I highly recommend it, I would definitely buy the same brand again and for other tools as well.
