I almost hate to give away my favorite place to get cartomizers, but for the sake of all that are interested, I will not get 510 cartos from anywhere except Mega cartomizers Nhaler. Those are the carts with the box that says "atomized cartridge" and also have soft tips. Never had a problem with them and have used them extensively now--I don't even really mess with regular atties unless I'm testing multiple different flavors and want to drip a little.
I've tried other cartos and I found them to be very cheaply made, even looking into the chamber you could see that the filler wasn't even put in well, whereas the ones from Nhaler are very professionally put together and last quite a while before needing replacement. I found the other cartos to also leak much easier than those from Nhaler--I'm glad I got lucky and tried them from Nhaler first, because I may have been turned off to cartos if the others had been the first I'd gotten. They also hold a very large amount of juice, over 20 drops in a blank cartridge, then I just re-wet it regularly so it doesn't get easily burnt. In time, the taste will start to get a little burnt and then you know it's time to switch to a new one.
