I was in the "I love auto batts" group before I got my eGo. I hated the idea of having to push a button. Now, I have been using my eGo manual for a couple weeks and w/ my eGo temporarily OOC, I'm using my 510 again...and I hate it. Manual batteries give SO much more control and better vapor. I don't even know how I put up w/ auto batts in the begining. I posted this in the New Members forum because I thought it might help those who are on the fence between Manual and Auto.
