I really wonder about those who give negative reviews because it doesn’t “detangle hair.” It literally says on the box that it is NOT for that use; it is for straightening and the hair should already be combed with another brush. It’s good to read the features of a product before buying it. Anyway, for fine hair and wavy hair like mine, it is very good.

They dry nicely with the brush and the hairdryer and do not frizz. The bristles of the brush might wear out quickly with frequent use because they are somewhat soft, but that way they don't hurt the scalp. However, I am satisfied.

It is strictly and only for straightening after you have brushed your hair with a regular brush. You use it only to straighten hair and NOT to detangle it!
The positive thing is that due to the hole in the middle, it dries the hair faster and does not cause frizz. The negative thing is that if you don't pay attention to the way you use it at that moment, it can tangle your hair.
Overall, I wasn't thrilled.
I use a simple tangle teezer for detangling and I also use it for drying, and I am very satisfied with it.

Too hard. No comparison with the classic one, which I also used with a hairdryer and after some years, okay, some teeth broke, but it was worth the money. I don't even use this one on my dog, it will ruin our scalp! 14 euros wasted :-(

From the second use, the teeth bent with combing and drying on straight hair! Not anything special, not worth the money!

I have had the product for about a month and I am satisfied. I use it when drying my hair after washing and it really helps a lot with straightening, it doesn't get tangled but dramatically reduces the use of a round brush with very good results.

Lightweight construction and ergonomic design. I only use it for drying and it does a good job. It helps to dry hair faster and without frizz.

Durable and ideal for what it was made for.
It doesn't break the hair with normal movements and detangles the hair without causing any strain after washing.
It doesn't serve the purpose of a regular brush, hence the "sharp" teeth, it is strictly for drying and styling.
It is unfair to evaluate it as a regular brush.

It really works perfectly, easily shapes the hair without breaking the strands or burning the brush from the temperature

Easy to use. So far, the bristles have not bent after 4 uses on very long hair, with a powerful hairdryer.

It was truly a completely useless purchase, it's not worth the approximately 17€ it costs. It hurts while brushing, hair breaks, and you definitely end up scratching yourself all over because it has very sharp edges. As for blow-drying, not only does it not make it easier, but you end up with a brush tangled in your hair, especially in the gap that is specifically designed for this reason, so that the hot air from the blow dryer can pass through and make things easier. But all of this is on a theoretical level, as in practice it fails miserably
