I recently purchased the Triton V2 tank after hearing good things about it be leak proof. Unfortunately I found the opposite to be the case. The first time I disassembled the tank to clean it, a small rubber O-ring came away from the base. I put it back on but when I went to fill the tank back up again. I left it for no more than 1 minute and the liquid had leaked through the base of the tank into the airholes and all over my mod! I have also found the drip top a lot harder to remove than the instructions suggest. Even to the point that I have had to use pliers to remove it. Overall a disappointing experience for £35.00
