very disappointed from yftk, my first and last buy from this manufacture. at first the mod came with horrible machining flaw , a big strip were the top and bottom of the tube is welding together , (look a the picture) and then the conductivity of this tube is a disaster, vary betwin 3volt and 3,30 volt! with a 0.13 ohm build depending on where you push the button. the 2 metal ring from the bouton make not a proper contact to the tube... maybe if I had bought this tube from another manufacturer I would have paid less and I would have had better quality

very nice drip-tip look very nice on much atomizer + panzer mod the o-ring is a bit to small but was an easy fix ..

in overall a good atomizer the glas cutting work is a bit rugue , the edge very sharp and in one was a little fissure metal parts very nice and smooth , chamber work well, no leaking, good vapor, all function well on the users pics all have the tayfun gt II logo, mine came without logo, only serial number.

nice aty for that little price. nice style on my panzer, good flavour , big clouds. positiv pin was a bit loose turning with by screwing the coil and causing a bit ohms jumping, fixed this with a bit coton very small betwin pin and insulator press it very hard in and work well now
