Interesting thread. I thought I read somewhere a while ago that leaving a charged battery in the PCC still slowly drains the PCC itself, but maybe I am wrong. And count me too as one of those that can't put the 510 battery in upside down. Simply does not work on mine.
I think they are great when you will be somewhere all day with no access to a USB port, wall outlet, or cig lighter. Other than that, I rarely use mine. What would be nice is if it were a bit thicker and I could modify it to hold a small dropper bottle along with 1 spare atty and battery..... all I could need. Instead, I went out and got a small case meant for portable hard drives and that holds everything I could need for any situation: PCC, USB charger, cig lighter to USB adapter, USB passthrough, bottle of juice, extra atty and extra battery.
I do prefer this to smoking and am glad to (hopefully) be done with smoking for good, but it is sure is a bit more work than a lighter and two packs of smokes.
