I can't recommend it. Set at low Volts it puts out at about 1V more so you still get either burn ejuice or sour taste. Using very high resistance coils helps a bit but here is another problem. Say you got it set at 3.2V only but as the battery gets lower you also get weaker vape. The idea I got Lavatube for is that it should keep same vape all the way and it doesn't. Also sometimes it misfires which seems to be common problem.
Another thing I can't stand about it is that the center pin sits too high and pushes all my posts up so for any other mod I have to pull them back again. This happens on the Young June model, not sure about the other clones but hear they have problems of their own.
So no I don't use it much at all and can't recommend it particularly to a new vaper who could possibly get health problems from inhaling burned ejuice because they don't have a clue about
vaping yet.
