TOBH atty v2.5 just came out and that is made from a solid piece.
I am not sure solder can leak from the other atties. Any one have any links for more info on it, it would be appreciated. Some one brought up the topic in the Ecig Juice Review G+ group and figured some one might know if it is worth looking out for or not.
