from what i can see this isnt a true VV device, it says it can beset for 4,5 or 6 volts. so you are losing a lot of funcionality unless you know you want to vape at just one of those 3 voltages.
there are a lot of evo threads but from pics it is not too much shorter then a vamo.
the new anyvape is coming with the option for different tube sizes.
