I have one but haven't actually used it yet as my plans for getting a chameleon have fallen through temporarily. It did take quite a while to arrive though because of all the customs they have to come through and you have to pay about £15 to get it through customs in this country once it actually arrives, but since it was the best that I've read about, I didn't mind too much about the money or time issue and one day will hopefully be able to use it
