I'll tell ya... I just love those 510 cartos! Like BK once said, an independent weather system inside the house with all the "clouds".

It vapes like there's no tomorrow. I haven't try to pry off the caps yet since everyone says they're glued on. I just top off through the battery end or use plunger method. Di, I haven't used an 801 since I got these. Oooh, fickle fickle!
