Today I was looking at my pile of old attys. I popped on a BE112 that I used all the time before I got my HV attys. I put 2, 3.7 batteries in my transformer and I have been vaping all day with it. This atty was ready to be pitched I thought. The flavor is good and I am still using it at 7.4 I am amazed. I wonder if any of my other old attys will do that.
