If you are talking about
this one, I have had my set for 9 days. It works very well, and I am happy with it. The variable voltage is great. I keep it at around 3.6-3.9v depending on the
juice. It's amazing much difference just a few tenths of a volt can make in both the flavor and vapor quality.
Take this with a grain of
salt. I have never used anything else to compare it to, so I really have no idea what I am talking about.
