I've got 4 different vaporizers, a Ego battery, a variable voltage battery, a GLV5v, and an Ascent. I haven't used the Ascent with any concentrates yet and probably will not. The Ego battery is a little too weak, the GLV5v works well but is a bit hot, the variable voltage works best for both taste and smoothness. I usually use the middle setting, forgot what voltage it is. It's so easy and efficient using this setup. Im all about being fast, easy, and clean. I realize that the nice water pieces with the hot nails, domes, etc. are probably the best to get the most out of smoking concentrates I'm just not ready to get into all that yet.
