Also, you guys notice how the chrome ring around the ego, where the button sits, is a smaller diameter than the rest of the battery? All the eGos with the rubber buttons that I've seen have this chrome ring the same diameter as the rest of the battery. I think it looks a lot nicer, it doesn't look like they hacked the battery together with a bunch of different sized tubing or something.
Plus if you use devices with eGo skirting they won't match the diameter of the top of the ego, the soft rubber button ones do. This allows it to seat better and be more secure on the battery. The eGo Mega Dual Coil Cartos (the huge eGo diameter cartos) will screw down and fit flush with the larger diameter button ring batteries, and be super solid and wobble-free. On all other batteries you really really really have to screw it down tight to stop it from wobbling.
Clearos with eGo skirting give me the same issue, they need to be extra tight to fit solid on most eGo batteries, but with the large diameter button ring ones, they rest on the top of the ring and seat solid without wobble.
I really wish more eGo clones were of this style instead of Joye clones, I can't stand Joyes compared to them.
Hvac,
You got a link for the batteries you're talking about? Sounds very cool, but when I looked for them all the ones looked like regular joye ego Clones with plastic buttons. Thanks!
