The Liquid bottle is very high quality and massive. It is absolutely tight and odor-tight, what was important to me, because I have two of them wrapped up in my e-cigarettes Case and I do not feel like that to me a leaky Liguidfläschen einsaut everything. Although it is a Joyetech XL case it goes straight to even, even if only comparable thin eGo batteries stuck on the other side of the case - but it works. The vials have also tidy weight!
