i use the 510 on my silver bullet, im still on my first atty, and its been 2 months. i blow them out at least once a day. at night usually, after i blow all the excess out, i do a dry burn at 5 second intervals untill the atty glows orange, and then a couple more quick burns untill the atty glow orange right away, and i can no longer smell the juice. then i stop. let it cool down. fill cart, 2 drips on the atty, and its good as new. i have never boiled as of yet, but maybe ill try that when my atty dies completely, but so far, this method has kept my first atty alive to this day, and is still going strong.
