Berserker V2 RTA top cap problems

[jakab]

I very much love the V2, but the top cap, which needs to be opened for refilling, keeps on opening.
Should it click or just turn? My tank is always leaking, since I keep on accidentaly opening the cap, just when normal vaping. Very very little pressure is needed to open the cap.

Does anyone else have similar problems? Is my tank faulty or is it just a design flaw?
I loved the V1.5 mini and I really want to use the V2, since it works great otherwise.

I'm having the same issue, I have two berserker v2 rta, and only one has this problem.
Did you solve it?
