Hello guys..I recently purchased a joye 510 from cignot.com for $35.00 no box and two units. I requested one auto and one manual battery. Neither one is working great....however the manual is doing better and i am thinking that it just needs a little breaking in. But the auto battery cuts off after 5 second and alot of times after only 3 seconds of inhaling and i dont get hardly any vapor at all. Is this normal? I purchased another 510 prior which i ended up giving to a good friend after i ordered this one, and that unit worked like a champ out the box, after the initial charge of course. Why would the battery cut off after 3 seconds? Correction, it seems like the manual battery is giving better and better performance the more i use it...and on both atomizers, but the auto battery is not staying on long enough to get a decent drag.
