Of the first three I got, one died after maybe 25 drags. Oddly, that was the one I had reserved for "dark" juices like Rath Waffle, Ms T's Caramel Chocolate Brownie, and Ms T's French Toast. The other two, I rotate daily (lighter juices only), and both are still going strong after about 3 weeks. The metal sheath is coming a bit loose from the atomizer part on one, but it still works great (leaks a tad sometimes). I just ordered two more today, and some HV juice. I love them, but we take our chances with experimental atomizers. It's best to know that going into it. If you don't like the odds, well, old style atties are still there... I'll play the odds myself. They are great on my Vypr!
Very well said Tempus Fugit. Every one should think this way when getting into the Low resistance attys. and in time they will get better.
