Yeah I LOVE my Chuck, there is absolutely no doubt about it. But I brought an eGo set, 3 batteries. At home it's my Chuck, at 3.7v, 6v is too much for me. At work it's my eGo since I work with kids and don't want them to see it. I see a very slight drop in vapor and throat hit with the eGo but it satisfies me. About to have the Little Sister too though which will become my work PV. The only things that are very hard to go back to are stock batteries, like the 510 etc. Unless you love the look of a mod you will probably still get use out of your eGo.
