I ordered some LR BE510 cartos from puresmoker.com. I was very disappointed that 2 of them were DOA and 1 poped after a couple of hours. The rest of them also popped very quickly. I dont know what i am doing wrong with these! I use a prodigy v3 @ 3.7 volts so it should be ok. I always keep the cartos wet hoping this will help with the popping problem. Did anybody eles encountered this problem? I just ordered some boge SR 510 also so im hoping these are better than the BEs.
