I like the Kanger T3'D the best on my MVP 2.0, but it does leak for some reason when I let the juice get low and don't use it for a bit (like over night). I called the folks I bought it from and they said I'm the only one they have heard with this complaint. The vape from it is so nice and the price is great though. The guy at the shop is going to call Kanger for me and see what might be happening. I've tightened all the possible leak points and secured the seals. I read another thread in which someone recommended storing the tank upside down to prevent leaks. I still buy and recommend this tank despite its issues.
