I'm having a slightly different leak problem with the XL Clearos (3.0. I also have a batch of regular sized 510 clearo's and they work fine (had to snip a piece of heatshrink on one of them to kill a plastic taste). The XL's work great after a clean and a fill (Running under hot water, patting down and dry-burning til the element is clean), but if I top them off or refill them without dissecting them for cleaning, it seems like the refill causes them to leak out of the hole on the battery side.
After blowing it out and cleaning the excess on the threads and mouthpiece, it's good for another few puffs and then vapor production drops off again, I get a gargle, and I need to blow it out, wipe it off, and go again. I've made sure the parts are secure, and this happens no matter how much, or how little liquid is in the tube, so it's not a filling issue.
I'm losing a lot of
juice because of this problem, and it's only 2 of my 5 XL's that do this. I love the flavor and vapor these things produce, and minus a couple minor issues, I like them much better than standard joye, boge or generic cartos. I'm switching to the IKV cartos, but I'd really like to salvage these if I can. Only had them for 2 weeks, and I rotate between all 5 so that I don't overuse any one.
Any ideas?
