These knives are very overpriced for the quality of the product. If I wanted to spend that much I'd go with the top of the line Global knives.

I'm not entirely sure why my husband loves this stuff so much, I just know that he got out of the shower (at a B Resort next to Disney World) and was like "Buy this please, my hair feels amazing." I went on Amazon and bought the conditioner and shampoo and three months later he still loves the stuff. In 11 years, it's the first time he's cared about shampoo or conditioner :) It does smell nice and a bit like tea tree. His hair is soft and he has no dandruff.

This is a wonderful product and I love it because it works, can be recharged, and keeps on working. Never a hurt with the new Yes no matter where you use it. Some products I've used, I use it once and then it dies but not with the Yes. Thank you so much for producing such a great product.
