Sue, I was just trying to elaborate a little more and give a better idea of the ego's size

. When I received mine, I was blown away by how small it was because I never did see any pictures of it next to another. In the pictures for some reason, even the ones I saw in someone's hand, I just got the idea that they were much bigger. Thats why I said earlier, that had I known, I'd have opted for the eGo Mega or XL because it is only slightly longer and you get alot more battery life.....if you do a search on the suppliers forum you will see some "Skins" if you want to dress it up some.
I do get quite a bit more battery life using the KR808 battery. That may be a happy medium. The PCC for the KR808 is much less bulky and is nicer than the 510 PCC, and for like 4 bucks you can buy a KR808 adapter to fit the 510s. The draw, taste, and vapor of a KR808D-1 are significantly different from the 510. I like the 510s better, some Cartos have a bad taste in my opinion.
