The mouthpiece gets really hot and the battery life is really short. So I would say this is good for beginners.
It does exactly what it says and works very well. Conserves flavor and there is no product waste! I do believe it has a few setback but, it is a cheaper vaporizer and I think these complaints are just the money-savers. It does get too hot to touch/use if you do two cycle to close together. Not good when your tolerance is a little higher so, definitely better for a more casual smoker. Difficult to clean since the chamber is not removable and does not come with instructions on how to clean your pen. I have to scrub with a tougher “pipe cleaner” after every cycle to make sure it is not clogged.
