Ahhh, interesting... and thats sad to hear. I guess it wasn't a good enough experience for you to believe in it then.
I have owned all of the ego type e-cigs, and i still don't use any of them myself
My friend works for Boge who make the Leo so i got to play with one a while back, it does put out a lot of vapor, but i think the attys are only 2.8ohm which is just 'ok'. The engineer said he's making big cartomizers for it too which will be really cool, but it's a disposable mod, so after x amount of charges or if it decides to fail you gotta keep buying the special Leo
batteries, just makes sense to buy something simple like a GGTB for 73 bux and use some 17670 / CR123A
batteries, coz if the battery flunks you just put a new one in, simple. I would say just buy a Riva for about 30 bux if you want something like a Leo to play with but you already have an ego so there's no point
