I just received a Ego 900 mah usb passthrough from LiteCigUSA which I am hoping is a genuine Ego product. Joytech lists LiteCigUSA as a trusted supplier and LiteCigUSA claims to be a supplier of genuine Ego products. My concern is that the battery recieved does not have Ego logo on it and the end cap (for the usb connection) is engraved with the LiteCigUSA logo. Is this genuine Ego or should I be concerned?
