Haha, well that's the weird thing, isn't it. My clearomizer didn't even last two weeks after I bought this thing for $60 bucks at a smoke shop in Rio Rancho... and nobody tells you this! So you're thinking that you may have blown away $60 on... hot hair (vapor?).
I bought a cartomizer for $75 that to me now seems it's just a disposable cig that you can get elsewhere for $5, so I really feel cheated. They scammed me. I never for either one of my purchases got any instructions, warranty or anything except what I got from them verbally. I had to get my information from forums like this. I can't help but feel people are getting scammed out of their money on crap all over the place getting them to buy stupid stuff.
But when my eGo works, I really like it.
I posted earlier that I fixed my cartomizer. It worked for hours, and now it's not producing a lot of vapor anymore. I have another Vision 2.0 cartomizer in the way, but this is just... not what you'd expect from a $60 device.
You know what I'm saying?
Oh, as for replacable heads, I think the Vision 2.0 clearomizer I orderd allows this, because I added a replacable atomizer thing with it for a few bucks. Price-wise it's not too bad, but will this thing even work on my battery? I just went and took the chance. There isn't a lot of good info out there.
It's trial and error. Which sucks.
