After going through most of the Kanger tanks and loving them except when they stopped doing the old style coils for the aerotank. I decided it was time to try to other tanks. So I switched to Aspire and their new Triton's, but they do leak on the of occasion too! I love this tank, the way it fills is brilliant, no small holes to aim for just squirt away, then the way it locks is another great idea, the flavour stays the same day after day with no dry burn, finally the air holes at the top so gravity won't let them leak! I'm getting another one next month so I've only one type of coil to buy. I'd definitely recommend them to anyone and everyone! I also need to add the customer service yet again as always is top notch getting the tank the day after I ordered it, thanks.
