Lots of vapor, good quality and battery life (I bought the extended life battery, also) and I especially like the charger because it is one of the few chargers on the market where the indication light actually indicates something and doesn't just change colors. My only complaint about it is it seems to cause interference with my radio so I have to charge it on the other side of the room and not near the bed.

I highly recommend you buy the USB passthrough. It's really great. I guess my only complaint the ecig itself is that the cartridge isn't very secure and I have lost a few carrying it in my pocket. Also, keep a chamois handy because if you drip, liquid can leak a little. It would be nice to have a gasket there and a better squeeze fit.
