Product review (1 stars): You will pay extra for a malfunctioning unit from Conair
Here's the thing. I have a bob that is above my shoulders length. I have semi-curly hair that I like to straighten.
Cons:
1. It pulls my hair out
2. Gets a little too hot
3. Button gets stuck going in one direction (right button) and doesn't stop
4. The smaller brush gets tangled and also pulls my hair out in even larger chunks (I don't use this one)
5. The brush does not spin when you put it on the cool shot setting (what's the point of having cool shot?)
6. Useless on the slow setting and can only use on high setting
7. Need an additional hair dryer to get it 80% dry before using it
8. The cord is extremely short
9. If it's not spinning, you cant use it as a regular round brush dryer because the bristles are so soft they don't go through my hair unless spinning
10. I had to put ducktape on the plastic ends of the barrel because my hair would get stuck in the crevices and get yanked out
Pros:
1. When it works right, it actually adds quite a bit of volume
2. So much easier than using a separate round brush and hair dryer combo
3. Since I have shorter hair, I do not have to use any clips to clip it out of the way
4. My hair is done in less than 15 minutes
5. No pain from my carpal tunnel in my hand when I style my hair
6. Handle width is perfect
7. Comes with cover so bristles don't get smashed down when sitting on counter (you will need to put it on after every use)

This product is far from perfect, but it works for my purposes. I don't expect it to be durable enough to quite last a year, especially with the situation with the button getting stuck in one direction. I would expect more from a product that's at this high of a price point. Since this one has many flaws, I may try another spinning round brush dryer when this one stops working. I haven't seen many that didn't cost more than this one. This one seems like it might be the in between model.

UPDATE 1/17/2017
Don't buy this product. It won't last you even a year before malfunctioning. Tried to return through Conair since my Amazon return date had expired. They'll let you return it, but only if you pay the additional shipping costs. I waited on hold for 45 minutes to reach a customer rep to be told this. I'll save you all the trouble. Don't buy this product because it's junk. If you bought the product already, make sure you return it in time through Amazon because Conair makes junk products. I've also filed a complaint about Conair via the better business bureau, which I found out Conair has an F rating on. I've never seen an F rating on the BBB for any company. Consider this a warning about all Conair products. I know I will never buy any of their products ever again. I already have vowed to never buy their crappy hair dryers that always break, but I'm extending this to all of their products after reading complaints on the BBB and due to my recent experience trying to return this spin brush.
