Deezy, I always thought those were called "condoms," but .... plug sounds much more fitting! I have actually had the problem that you've described, but I don't see it as a problem because when I take off the ".... plug" I generally fill it up at the same time through both ends

.
Basil, I don't know why you're coming on so aggressive, but I am saying what MY experiences were. I did use it quite a bit in the course of a week and then didn't charge it 'til the end. I suppose maybe the fact that i used it with long intervals between each use could have somehow affected the battery life; I don't know.
On another note, two hours for these batteries seem WAY off. Unless you're puffing on it every two seconds I don't see how you could deplete the battery that fast.
For future reference, if you have something to say to me, don't be an ... about it and bad-mouth me right on my thread; I'd appreciate it if you just send me a PM and I will fix it if it actually requires mending.
Hating on forums is pointless.
Peace,
Evan
