I"ve seen people comment that the Triton tends to leak, but I've had mine a few months, it's the only thing I vape from, and the *only* time I've had a leak is when I've been trying to push a coil well past where I knew it should have been changed. Somehow this messes up something with the flow through the device, and I'll get (small) leaks from the upper vent if I set it down in that condition.
I've never had a leak from a coil that was not worn out, and I love everything about this tank. Unlike the Triton 2, you can't fully disassemble it, but I think there have been some different complaints from the Triton 2, so pick your poison I suppose.
