Product review (3 stars): Not for short hair
Against my better judgement I bought the 2" model and cannot use it since it is just too big for my layered, shoulder length hair. Sadly, it's not eligible for return, so make sure your hair isn't too short before you buy this product.

I still gave it 3 stars because the product itself seems good, but I wasn't really able to evaluate well, so no more stars than that.
