me too,
I have had my bestecig 801 usb on my pc since nov,
it is still going strong, most all day use and constant puffing. very good piece of kit.
I have my David Yang 801 usb manual switch plugged into the wall socket adapter beside my recliner and that one gets used all evening also puffing constantly,
and if I go out, this one goes with me,
with my mobile power pack,
this one is going strong since xmas day.
these really are the very best things available for e-cigs......
