Okay, so i got the sentinel m16 clone vape. Was working perfect untill the top cap screw piece on it( that connects the tank to the vape ) the thread on the piece got screwed up so it wouldnt fit any tank on it, So i bought a replacement piece and it arrived yesterday i put it on and for some reason it doesnt work? my battery is fully charged nothings wrong with my tanks, at first it worked for a second but only produced a really reallly tiny amount of smoke, so overall, what can i do? i know its the right piece but my vape just wont fire!
