Jose Eber Hair Straightener

I was recently in a department store in the United Kingdom where a girl has been the promotion of Jose Eber Hair straighteners. The funny thing about this iron is that it is not hot (it does, but his hand on the little that is usually very hot). She said something positive and negative, but I have not had the time ....

But now, sort of interests me as I'm constantly straightening my hair (I use GDH) although it is very thin and I'm worried about the damage.

Does anyone know about this product?
Does it work, even if it is not hot?

frees probably positive and negative ions. I've never heard of that
