Something broke inside after a year of light use so the brush is no longer stable but still usable. Both brushes rotate and they are harder/more solid than similar Chinese brands. Good for short to medium hair, tangles anything longer.

I have straight long hair with normal texture that tends to frizz.
Initially, you need to dry your hair and ideally it should be damp. All of these definitely require heat protection.
On the positive side: it tames frizz, has moderate weight considering its volume, has good airflow for a nice blowout, takes a little longer for loose curls.
On the negative side: personally, it is highly dangerous that it rotates. It requires a small section of hair so that you don't have to search for your hair and have it well combed. It rotates very quickly and can gather your hair. It has a short cord, about 1.5 meters.
In summary, it has to do with the hair type. I will buy it again as a gift for my mom who has the same hair type.

I bought it to do a light blow-dry after drying. It's fine, just before you start pressing the button to turn the head, do a test first, it turns quickly and the first time I almost got tangled! Otherwise, it's perfect for its price.

I have straight, thick hair, cut below the chin. It does a very good and easy styling, almost takes the curls on its own and turns them without even making sections. Maybe for the length of my hair, it would need a smaller brush for a tighter curl. Edit 25/9/23 with use once every 15 or one rotation, one broke and the other sticks...

For short hair like mine, it is ideal. I use the small brush which, of course, is not very thin. There is difficulty in removing the large brush from the base to the point where you think it will cause damage. That's why 3 stars and not 5.

It is not absolutely suitable for long hair: it tangles for a long period of time and poorly.
It is not worth its money!

When I used it, I saw that it is very good and it keeps the hairstyle!!!! Right, it doesn't damage the hair.

Very good, it doesn't damage the hair, the hand doesn't get tired, what can I say about the price and its use, I have no words. I dry and style them at the same time and it's like I came out of the hair salon.
