I have long, wavy to curly, quite frizzy and dull hair. I used it on damp hair along with heat protection and within 10-12 minutes they were dry and styled. The result was a very beautiful blowout with lasting effect.

A lot of hype for nothing, yes it will do some styling. But that's it! And I don't know how much it damages the hair! I gave it to my little sister who has wavy bob hair!

Much better than a hairdryer + straightener. It helps a lot with frizz. Large size and relatively heavy.

The picture does not show the HUGE size of this device. It is really HUGE and is only suitable for very long hair. I have medium-length hair, and I think I will have a lot of trouble using it. I will keep it because I plan to grow my hair longer and maybe it will be useful then. Until then, I bought something that seems useless for now.
Update: After using the device, I have to say that it makes the hair frizzy. A lot. Because my hair is layered, the frizz (even though two different products were used for heat protection and anti-frizz), the device made it a mess. I mainly got it because I wanted to get rid of the straightener and in the end I wasted my money on this nonsense. Useless thing.

I purchased this 40 days ago and always used it correctly on dry hair. Unfortunately, the device burned out and completely stopped working. I expected much better durability and quality.

It is very good for saving time. It dries the hair and at the same time you can style it as you want.

Nice brush but I saw better results from brushes from a well-known German supermarket with a detachable head

On the positive side, it has a large head and grabs a lot of hair at once

On the negative side:

It makes excessive noise
It does not have a detachable head and you cannot wash it. It gets dirty very easily and cannot be cleaned

Purchased due to the large number of positive reviews and the affordable price.
Average experience, quite heavy in the hand as many mention if its use exceeds 5 minutes.
It gives a light styling helping with frizz, but with short duration. With more passes the duration increases, however you lose quite a bit of time.
If you don't want to use a hairdryer or straightener further, it gives you an okay smoothing of the hair.
Conclusion:
In general, it did not disappoint me to the extent that I would want to return it, however, it's not something you will miss if you know the basic use of a simple round brush for styling.

I have straight, long but thin hair. I bought it purely to give volume to my hair, personally I found it a bit difficult to use for my own standards.

An excellent value for money electric brush, the result for me is much better than with a hairdryer and round brush. However, I have straight hair. It works better on damp hair and cuts the time in half

I have fine but a lot of hair, long down to my waist, straight up to the jaw and then it turns into curls, generally very frizzy. I imagine it would be much better for someone with straighter hair who mainly needs styling. Personally, I got it as a preparation step before the flat iron because, of course, on its own it is not possible to straighten a hair type like mine. Maybe I need to try the maximum heat setting, since the first level is not hot enough. The size is very convenient for quickly smoothing everything out. For me, who is not particularly good at using a brush and hairdryer, and for what I want it for, it is satisfactory

I expected something very, very different as a result. It is a bulky tool that, okay, with proper use can bring a satisfactory result.
If you are good at using a hairdryer and brush, I consider it unnecessary.

Light and very easy to use, I have long hair. The brushes are not stiff enough to stay in place, on the contrary, but it's worth it if you want well-groomed hair.

It's worth the money, for me it mainly straightens my hair but maybe it's because I don't really know how to make it curlier... in any case, it's an economical and quality choice and it does its job.. on the downside, I would say that the bristles of the brush have somewhat wrinkled

Quite good for its price. Surely, in a short time, especially on already dry hair, you can achieve a decent straightening and shape. It doesn't give volume that will last, although in general my hair doesn't hold volume. So I didn't have high expectations in that regard. It would be more convenient if I didn't have to use it when my hair is almost completely dry. This means I lose time with the hairdryer plus this afterwards. But it's quite fair. I recommend it.

The best purchase I have ever made. Even with the first use, the result is as if I just left the hair salon! I chose it because I am not good at using a brush and hairdryer together. I did a light drying first with the hairdryer and then continued with this brush. I highly recommend it!!

It's terrible. It doesn't give a nice airy blowout like at the hair salon, it's more for straightening your hair rather than giving it volume. In my opinion, it's not worth it at all

It is a useful tool, especially if you straighten your hair often. It is 2 in 1. Both drying and straightening. Of course, the straight hair has quite a bit of volume, it doesn't get pin-straight, at least for me. I use it on both dry hair and 80% damp hair. It gives a very nice salon blow out, I believe it takes a bit of practice to learn how to use it. My husband also uses it for his beard

Terrible product girls don't buy it it ruined my hair and I had to cut it from waist length to a short bob really worthless

The product is not for drying hair! Your hair should be damp to almost dry when you use it. For me, it gives a very nice blow out that lasts until I wash my hair. Use a heat protectant before using. 5/5!

This brush has changed my hair routine! Now my hair is styled 24/7. I have long, slightly curly hair and I can straighten them in approx. 20 min. I also have layers and I can style them easily, by just twisting the brush 2-3 times. It is quite big, but not heavy at all. It is loud, but so is my hairdryer, so that's not something that I take into consideration, but someone else might. I leave one star out because I cannot clean it efficiently.

It straightens hair more easily, but it requires technique for curls, etc.
Hair should be dried with a hairdryer first, about 80%.
Easy to use

It is good if you are in a hurry and you need something to dry your hair. But after few hours are getting frizzed and curly again… not so strong for thick hairs like mine. It doesn’t gets the roots done

I bought it and now it's just sitting there, a waste of money! It makes my hair super frizzy, doesn't straighten it, no results!

Simple to use, lightweight despite appearing bulky, makes it easy to use with one hand. Hair must be damp.

I would not recommend it. I feel like it burns my hair and causes split ends. Also, it does not hold the result, at least on my hair. Finally, it is very noisy.

It is a good product and it really can dry your hair and the roots well. I have wavy hair and the truth is that it styles them quite well, but I would like it to style them a bit better or give a little more shape. Now they are just everyday well-groomed with very nice volume. It does not help if you want them to be more well-shaped

It dries, straightens, and smooths the hair. It is only large in size and cannot be used for curls.

I wonder why I hadn't bought it all these years... I'm incapable of using a hairdryer with a brush, I have wavy hair and I recently got a layered haircut. In 10 minutes, it's like I just came out of a hair salon. I can't believe it myself. First, I dry them with the hairdryer and then I use the brush with movements I saw in a video... Also, the style lasts fully. I recommend it!!!

It provides very good styling with lasting hold. The only downside for me is that it takes quite a while to dry the hair, so it requires the hair to be almost dry already.
