I got it from my cousin who purchased it from a smoke shop a few months ago and he upgraded and handed me his. It couldn't stay on a specific mode (watts, memory , or temp). While having this problem with it, it kept changing what it burned at and it got fired for .3 seconds on 220w, and after I can swap out tanks and coils and all specs rise as fire is activeactive and displays no warning but doesn't fire. It has an wonderful baby beast tank with a single mesh, but downfall to it is the seals don't quite fit properly on the tank.
