Just throwing in my two cents of experience with these LR attys...
I got one with my Phidias Woodimus and purchased 6 more when they first became available.
ALL 7 of them have worked and continue to work as expected. All were in the 1.5-1.6 ohm range resistance and no DOA or popped/fried attys.
I have used these primarily on my Woody and Silver Bullet with the LiMn 18650 High Drain battery. I have also used it on my XHaler with an 1800 mah 17670 L-Ion protected battery.
Besides the huge clouds of vapor at standard voltage, I have also noticed that these attys at 3.7v operate very similarly to how a std. atty does at high voltage. They get hot faster and use a lot more juice than a std. Joye 510 at std. voltage.
Many folks who have not used high voltage mods before are experiencing the same learning curve that high voltage vapers experienced with their first HV mods.
There's been a lot of good suggestions here for getting the most out of these LR attys.
The most important to me is: Keep them wet and keep the drops coming!
I look forward to the continued development of the LR atomizers and hope they get a bit more affordable in the near future
