I own a ridiculous number of mods and this is the best mod I have bought in quite some time. The craftsmanship and build quality is fantastic. It's a solid and heavy mod which may put off some. Everything just works no battery door rattle, button nice and clicky. Simple menu system the only minor downside is that you can only increase the wattage by 0.5 increments rather that the std 0.1. The paintwork is also really well done.
