I put mine through a wood chipper just to see how resilient it is and it broke the wood chipper and came out looking good as new. LOL
Seriously though, I've had mine for about two or three weeks and use it often. I have two cells, vape on one while the other charges (and they don't take long to charge at all, which is pretty awesome), and everything is holding up great.
The only suggestion I'd like to make, maybe
@Innokin_Ash can submit this to the designers, is that the cell does sometimes slip off the Disrupter. Not sure how that could be fixed... My Kanger Sub Tank Plus is a little larger than my other tanks a drippers though, so that does hold the cell on nicely.
Also, just wanted to mention something some may not know because they're like me and didn't read the manual LOL.... My son actually discovered this by accident..... If you press the little LED on the cell it will light up to tell you what level your battery is at by the different colors. Green OK, Yellow getting low, Red time to charge. I like that feature
