Ok, so I bought my first one about a month ago, and it works so great that I ordered another last week. They've replaced my old ego 900 mah batts and ego booster. Very glad for that as the booster wasn't very well made. But who makes these batts? My Dad bought one that looks identical while he was in town from my local shop, and his has the plastic frosted white button, whereas both of the ones I got from FSUSA has a metal button. Neither of these types are true egos as those have the smokey grey hard plastic buttons (feel like those are slightly better quality than these, but I've had no problems), but I don't think Joyetech makes their own version of these anyway. Just curious as to who makes these. One of them has a messed up LCD as the top light bar doesn't light up, but it's a minor thing.
