lol @ Amy. For some reason the Mega atomizer that I bought from heavens makes butter rum taste NASTY and burned. I blew out the primer two nights ago and used a 510 battery and got no problems, I guess I'll have to do a really good cleaning on it. Any other atty is heaven tho. For having my chuck for only five hours, Ive gone thru 4 diff flavors already, this thing is just plain incredible, hands down. Like everyone else says the ONLY possible flaw I see is the switch, but hey, it works AND looks awesome. I already went to the campus bookstore, ( I work for the University of Mississippi Medical Center) and bought a cell phone case that fits my Chuck perfectly and will let me carry 4 loaded up attys with carts, an extra battery and a few small bottles of juice. I see me drip tip about to get used heavily. This thing burns thru juice like its rocket fuel!
