you must be lucky- i found the kanger t3 not verry good at all-- at first i thought wow-these rock!!!! but soon started getting dry hit every 4 puffs or so... tipped upside down-swirrled it round ect same problem.. using 70pg 30vg so juice is thinn enough.. changed coils and the new one just died after a few puff... the next coil worked good for a week or so but still got dry hits every 4 puffs or so.. at 2.5 om i thought you may be able to turn voltage up but anythin over 3.7 i got burnt taste. they are really easy to refill dont leak but i think the wick is probally too small.. i wanted to like em but now there in the junk draw....
Lift the silicone a tad before putting it in and don't overscrew. It settles into the right position and you'll no longer have dry hits.
