Finally got the ego kit. It is a world of difference between the blu and the ego with 2.0 boge carto's. I am loving it. The batteries last me almost two days. And the vapor is wonderful. I thought had a glitch with one of the batteries at first ,it would not
charge. E-mailed Liberty-flights, they answered in a flash. Sent a new battery and a return prepaid postage sticker to return the battery. Well come to find out it was the carger that was bad. So I e-mailed again, and they sent me a new charger. I
am very happy with the ego, and liberty-flights customer service.
