I purchased this to replace a similar tool from Revlon (I forget the name of it, but do not buy the Revlon one. It comes apart, needlessly, and can never be properly reassembled). I really like it.The point of my owning this is to avoid having to do a blowout with a round brush and separate dryer. I do not possess the ninja hair skills to operate two items at once. I am also extremely lazy. So the reason this does not get 5 stars from me is because it does not have the blow-power to really dry hair; it is more of a styler. My thick, shoulder-length hair must be nearly dry to achieve the quick smooth style I want from this tool. I either have to let it air-dry for about 45 minutes, or pre-dry with my blow dryer. (The Revlon tool did a better job of drying-while-styling, so I know it is possible.)Having said that, I really do like this tool. It smooths hair as well as my salon stylist can with a round brush + dryer. To be truthful, if it blew harder it would probably not smooth as well; the hair shaft is like a series of little shingles, and if you blow them the wrong way they get roughed up and don't reflect the light well. So I kind of forgive it for not blowing harder. (I really should be less lazy, but I've got a kid and a day job and better things to do.)The large diameter of the brush is refreshing. It provides a straighter style while still giving me plenty of volume. The narrower brushes gave more of a curl/wave thing. I do like that the result from the Babyliss mimicks a plain blowout.The Babyliss feels substantial in the hand, well made, not toy-like. It feels as though it is built to last. (It better--this was much more expensive than the Revlon.) The titanium barrel is instrumental in the smoothing action.There is a bit of a learning curve with the rotation, or at least there was for me. The rotation buttons are a hair trigger, and I didn't even mean to make that pun. Just lightly touching them and you're spinning. So it was a little fiddly for me at first. Sometimes I want to just spin. Sometimes I want to roll the hair to the root and hold the tool close to my head for a minute. Getting the finger off the button at the right time is a little tricky. But I did mention I have zero hair skills. I love that it spins in both directions. It spins very smoothly.I was afraid I would tangle up my hair in the rotation process. It has NEVER tangled. I'm a little bit shocked. The bristles are just perfect; the perfect length, the perfect amount of grip, and when it comes time to clean the hairs out, the bristles let go of them quickly. Very easy to clean.I have never burned myself, either. It is not easy to grab it where the hot barrel is. The bristles keep your hand away. I like that. The tip is hot, though. Careful.It came with a little plastic sleeve that I thought was just packaging, but I ended up keeping it to store the brush in while not in use. If you stored it lying on its side--as I do--without the little sleeve, the bristles might flatten over time. The sleeve thing is perfect for popping over the end to keep that from happening.I like that it has a cool setting to lock in the style; I like that it doesn't spin while on cool. There is no need for it to spin at that time, and I appreciate Babyliss' attention to this detail.I wish the barrel were a little longer--so I could wrap more and more hair around it, furthering my goal of extreme laziness--but it's okay that it isn't. It really is plenty long for most normal, non-lazy people. The bristles are long enough that you can wrap what is really too much hair around it and it will still work.I would repurchase this item if I needed to. I would recommend it to others. It works great. The price is reasonable for the quality and effectiveness of this tool. I hope this review was helpful to you.I have another blower but wanted one that rotates. I do like this one but it is an adjustment. The heat does seem as hot. And the rotation takes some practice.Terrific product.I moved to U.S. from Europe where I had a hair dryer with a rotating hair brush. I loved it - it had two exchangeable brushes of two different sizes and you could also use it without a brush to pre-dry your hair. I left it in Europe because it worked only with 220V. I thought there will be large selection of similar products on the U.S. market. But I was disappointed. First, I found Conair Infiniti Pro Spin Air Rotating Styler. It actually looks and operates in the same manner as this Babyliss Pro Rotating Hot Air Brush. However, the first time I used the Conair, it was already malfunctioning - brush rotating very slowly or not at all. Although the sedond time I used it, it worked perfectly and gave my hair beautiful shine and my hair was smooth and frizz-free. The third time, it worked only intermittently and the fourth time, it stopped rotating completely. I returned it and looked for another hair dryer with a rotating brush. Unfortunally, not many of these on this market :(To my happiness I found this Babyliss. The brush is larger which works for my shoulder-length hair. It rotates better and faster than the Conair. It produces more heat than the Conair. True, your hair dries little longer than with a regular hair dryer, but even if you take the extra minutes that you must have using Babyliss and use them while drying your hair with a regular hair dryer and classic brush you will not achieve the smoothness and shine of your hair. I guarantee it. You can always pre-dry your hair with a regular hair dryer that you probably have at home anyhow. I used to pre-dry with my European version of rotating brush. Because Babyliss does not have this option I gave it 4 stars.When using rotating brush for the first time - it takes a few times to get used to it in order not to tangle your hair. Especially, if you are left-right orientation challeneged as I am - especially when you have to coordinate with your image in a mirror. But after 2-3 times using it, you'll master the two buttons you have to push in order for the bursh to rotate in the correct direction.From what is available on this market I highly recommend Babybliss with rotating brush - it will make your hair look like from a hair salon with shine, smoothness and no frizz.No es un producto malo pero yo uso secador profesional y de nada sirve esto! Si usas secador casero con poca potencia puede ser útil, en mi caso al estar acostumbrada a mayor potencia, calor y rapidez automáticamente sentí que perdí mi dinero. El otro punto es que las cerdas con un solo uso quedaron súper dobladas. Que lástima porque todos los propose la marca son muy buenos.Pésimo producto. El secador no tiene fuerza y casi no seca. El cepillo no agarra bien. En resumen el peinado queda desastroso. Ojalá pudiera regresar porque no sirve. Además es carísimo. Cómprate un Revlon.I am an older woman, and have very fine hair, shoulders length. I also have hot flash galore when I dry my hair. I tried this yesterday for the first time and have to say that this will be my next favorite tool. I think I put too much products in my hair and not dried it enough before using the hot air brush. However, I had tried it on dry hair and it worked great. Make sure you dry your roots with your regular hair dryer so the brush will be more effective. As I said before, I have raging hot flashes when I dry my hair (why???) and so i'm having problems with drying the roots. Next time, I will completely let my hair air dry and then apply a light spritz and use the brush.You also have to get accustomed to the button that makes the brush roll. But it should not be difficult. It will not thight your hair so hard that it is uncomfortable. This tool, I think, cannot be used alone as you need to almost completely dry your hair before your brush can get you volume. And it will not give you curls.I am in love with this rotating brush! I have zero ability to style my hair and have never been able to successfully blow dry and use a round brush simultaneously. This brush works great on short/medium length hair. I got it specifically to style my angled bob and to provide volume at the roots. I like how there are 2 speed settings: low has a slower rotation and blows warm air, high has a faster rotation and blows hot air. The bristles are very soft and don't hurt your scalp while rotating. However I can see how with longer hair the bristles might not be hard enough to grab the hair. The buttons for the rotation are conveniently located and rotate forward and backwards. One thing I want to share is that after watching many tutorial videos on YouTube I noticed that this brush is being used incorrectly. The rotation is not meant to be used continuously which can result in hair getting tangled around the brush (especially for longer hair). The rotation is supposed to be used in short bursts then released with the hair held in place. Overall this has made my life a lot easier and allows me to actually style my hair which I couldn't do before. It is an expensive product at over $100 but I am hoping it lasts for a few years.I find it awkward to use, it leaves my hair with lots of static and does not give the full volume that it says it produces. I have also tried the Infinity PRO by Conair... and find that this one works far better and at half the price. It is good to note that while I have thin hair, I have a lot of it and it is shoulder length and typically curly. I will continue to use the Babyliss Nano, as I did buy it - but I still need to use my other hair appliances in order to get ready for the 'day'. Wish I hadn't thrown out the packaging.. or I would of returned it.
