Product review (5 stars): Love this spin air brush
Love this spin air brush! I had previously used something like this: Infiniti Pro by Conair Nano Tourmaline Ceramic Hot Curl Brush; 1-inch, that broke after about 2 years. I cannot comment on the longevity of this brush yet, but I love that it uses air instead of just heating up. My hair does not feel damaged after using.

For me, there was a learning curve (2 uses) to get the whole motion down. So if you have a similar experience, do not worry. I have bra strap length hair that is naturally wavy, blonde, and pretty thick. This takes me about 5-7 minutes to do my whole head. I can do very large chunks of hair with no issues. My best tip would be to make sure you are holding part of the section of hair while using the brush so that the hair doesn't get caught in the rotating brush head. If it does, it's no big deal, you just brush it out.

You can definitely use this to add volume or just smoothe your hair, just like a normal blow out. The device comes with two different sized brushes and some plastic protectors for the brushes to keep them from getting linty/dusty between uses. I think that is a nice touch even though it is just cheap plastic.

If mine breaks or stops working, I will update this post. For now, I am very pleased to find something that does not damage my hair too much and allows me to look presentable for work/church/going out in under 10 minutes.

Note: this brush does not get super hot. If you need it to get super hot, due to your hair type, I would not buy this brush. The rotating feature and air helps, but it is not a straightening iron.
