Apart from the rotating brush, I found the other attachments to be useless. The plain round brush might serve someone with short hair, but for me with long hair, it was a bit useless. The straightening tool seemed to take much more time compared to a flat iron. The regular comb is obviously just for drying your hair.
Now, for the main brush, I don't have anything particularly bad to say, but I didn't throw my hat in the air either. I feel like it should have more bristles to better hold the hair. The way it is made only holds small sections, which takes a lot of time if you want to do it properly.
I used it with very wet hair and completely dry hair. It works equally well either way. I feel like a more experienced girl would do a great job with this electric brush. As someone who is inexperienced, I manage to have fairly nice hair with a nice movement, not just flat and straightened.
It is not heavy and does not tire the hands, which I find quite important, and you get used to the rotating button after the first 2-3 times and do it automatically after a while.
I think it is worth buying, just maybe the plain version without the extra attachments - the 4 stars go there.

I have a correction after a few months of use. The joints of the moving part of the brush, on the sides, when you take large sections, get stuck in the hair and pull it. It is very annoying and painful. Also, it doesn't work at all on already dry hair. Only on wet hair
