I came across these about a year ago. I was doing my dermalogica training (i'm a beauty therapist) and the woman doing the demos kept using these cloths. I was amazed. So much more hygienic that a loofah! And a lot more effective! I love that once i've used it, I can just put it in the wash and it'll be like new again!
It makes my skin feel beautiful, without having to spend a fortune on various exfoliation products.
The price however is a little bit much. But I had to have one! However recently, I came across a cloth just like this but it was a Sanctuary one, costing me only £6 off the internet. So I bought one for my friend! She wasn't disappointed either and now all my friends own them!

Overall, I would consider this to be a necessary purchase if you care about your skin. It's very effective, and hygienic. (But if you can find a cheaper one somewhere, do that instead!!)
