I recently went to a local B&M and bought an ego battery. I noticed that the batter lasts maybe 1/2 an hour until the orange light begins to flash. I checked the verification online and it was verified over 16K times. I'm frustrated because this seems like an honest shop, but I've been there twice to return goods because they were incompatible with my clearomizer and now I have to go again because of this issue. Does anyone have any suggestions of where to buy authentic products but have decent shipping rates and fast delivery times in California?
