I had a lemo2 and the best day it had was when my college knocked it over and broke the glass. Lemo 2 had the lovely top fill and not the horrid base screw but flavour was superior on the lemo1.
Ya I hear you. But I'm not too worried about that screw. I have a screwdriver that is magnetic and it picks it up after unscrewing it. And easy to put back.
Also with the tank capacity and the way I vape it I only refill it every few days. Would be a hassle if it was a few times a day!
Another thing. Amazingly that screw has held out for about 4 years. Can't believe it. No problems.
