auto batteries used to have sensors that would activate to sound or wind. Had a batt in my bra at a nightclub in 2009 and it starting firing and shocking me (due to the bass and vibrations of the music)... it was QUITE the SURPRISE!!!
The technology has just gotten better...so vapers who have not revisited autos since going to their fatt manual batts, just don't realize it.
When I first started over two years ago it was with 801's on auto batts. Those dern things would fire if my son passed gas in the same room. Okay - That's a bit of an exaggeration, but not by much. Sometimes the LED's would light on the end table for absolutely no reason that I could determine at all. I still have a few of them in a clear box. Whenever I move that box, the LED's light up. Most disturbing. An awful lot of people have no idea that the technology is so much improved now.
From there, I went to a KR-808, but I had too much trouble fighting with the connectors and getting them to charge properly and the vape was COLD. That was it for the auto for me. On to the Joye510's which I fiddled with for waaay too long. Tea bags, foam, scrubby pads, springs, silicone, straws, different cartos, etc, so on. So I tried 510 tanks which didn't taste right. Pump carts, SmartCarts, CE2's, G4's, in addition to eGo's, eGo tanks, Leo's, and Lea's. It was a ridiculous struggle.

Who woulda thought that the unimposing little Volt could beat them all in a fair fight? I finally found my way HOME!
