i've had my 510 for 3 mos. now and it's been great so far. my two attys are still working like champs. Also, i don't know why i took so long to take the cotton thing out coz when i did, and started dripping, i noticed a pretty nice vapor production increase, so i'm all over that. one more thing, i've dropped my 510 a few times now, and i just dropped it today when i got off of work, and when i got home i noticed that the little white round piece that covers the light on the battery is GONE!!! lol...its so much brighter now, cant wait to vape at night now...LOL.
