i had given up on cartos some 1.2 years ago. my local vendors had only some noname ones and none of them worked. it was the time of the syringe mod tank and i was using it with these cartos from the local vendors. anyway, i decided to buy a smoktech carto tank, which was the tank itself, a cartomizer with a tiny hole and flanges and a drip tip. the smoktech carto tank worked flawlessly since the first fill. it was then that i discovered the smoktech cartos and im still using them in my tanks. the single coil 1.7-2ohms are very very good. they work better with thiner juices but not too thin a 70/30 pg/vg has never given me problems.i DIY my liquids so i have full control over their composition.
things are a bit frustrating some times with these devices. they are hand made in china so don't expect too much in terms of precision but they are good in general terms and really do work.
