If you are near your euros, and don't want to spend too much on the Kayfun 3.1, get this one.
Real low price, for such a high quality atomizer.
i have the 3.1 and the lite : *sometimes* i can't even tell the difference if i don't take a look at the atomizer (except for the weight :) ).
Good in all ways.. you've got your euros well invested !
