Review (2/5): Great idea but...
I have thick, long, wavy/curly hair and was excited when this arrived as it seemed well made & collapses to a very compact size - my normal Solano diffuser works great but is big, bulky and takes up a lot of space when packed for travel - and then I tried to use it. It seemed to fit my HOT Tools tourmaline 2000 dryer, but as I dried my hair and the diffuser got warm, it slipped, collapsed, and wobbled from side-to-side making it impossible to use. Unfortunately, this is being returned.
