By far these are the best hair straighteners I have used. They far exceed GHDs. These Jose Eber straighteners do not snag the hair at all, they glide and feel glass smooth. My hair is extremely thick and unruly and the straight results with these last a lot longer for me.
The downside for me is that they become very hot and personally I would prefer a grip at the tip of the straighteners to hold them shut (although this is not necessary) but the straightener becomes far too hot to be able to do this. Apart from that, as I say, these are much better than my GHDs (and countless others I have owned including Babyliss).
