Just a note that I don't intend to be a negative review of ENS or the product itself, but I have two plastic J-tanks, one 5.5mL and the other a 3.3mL tank. One of the things I worried about before ordering was whether or not I even own a juice that is known to crack plastic tanks. I did a little investigating and found that all the juices I vape are supposedly completely safe for use in polycarbonate and polypropylene tanks.
Yet, BOTH tanks have developed cracks. So far only the 3.3mL capacity tank is unusable, but it's only a matter of time until the larger tank's cracks become....larger.
That said, I love the J-Tanks and they have worked perfectly since I got them until recently when I noticed the cracks.
