Review (3/5): it has the WORST button/switch type and placement of anything I have ever ...
Disclaimer: I have curly hair, so I have only used this with the diffuser.
Pros: It does what it's supposed to (dry hair!).
It's not too loud.
It's sleek looking.
It comes with a diffuser.
Cons: For crying out loud, it has the WORST button/switch type and placement of anything I have ever used. Ever. Why on God's green Earth they decided to put those particular buttons/switches right where your hand goes, I will never understand. Every time I want to move it around, I have to make sure I grab it in the right spot so I don't change the heat setting or air flow, or completely shut it off. The cool-blast button is also exactly where you want to put your finger when you hold it, and it presses with next to no pressure. I either have to hold it by the very bottom of the handle (awkward, it's top heavy), or over the air intake (also awkward, my hands are small).
The diffuser has rough plastic spikes (? not sure of the correct term), and sometimes they catch on a curl and completely frizz it out (it looks like I brushed it D-: ). My old dryer had a smooth plastic diffuser, and in the 7 years I had it, no curl ever fell victim. Not even once.
Overall, I probably wouldn't recommend it due to it's ergonomic issues. That said, it's all about personal preference, so I wouldn't not recommend it, either. Just be aware of the button issue.
