In the series of dna mods I want to continue with VT133 from hcigar. It is 133 watts device with DNA200 chip. Works well, with great great looks, perfect massive 510 springloaded centerpin. Only one problem I see is the paint on battery cover. It goes off very fast because of sweat. You just need to do new paint job after some time - it is normal trouble of zinc alloy. But at all I love this mod.
