There is nothing to excuse. It is a fair point, being concerned about the quality of the device. And it isn't an official ego, made by Joytech. What made me pull the trigger on the device itself was the lifetime warranty on it, provided by apollo. Their chat staff isn't on right now, what with it being a holiday weekend and all, but they will tell you they offer a lifetime warranty on the product, free from any and all defects, even the one's that you KNOW are coming (like the ego eventually not holding a charge, since all rechargable batteries inevitably die). They promised that as long as I kept my order number saved somewhere, I could give it to them, and they would replace the product - no questions asked. That is what alleviated my concerns.
I got the 1200mah battery, which is an absolute beast compared to that Kanger, and have been happily puffing away since.
