Best/cheapest place to order Aspire BVC clearomizer atomizer (low amp 1.6) online? Also a question about atomizer longevity.

So these attys are only lasting me 2-7 days. I've tried different amps and stuff. These are the first ones to ever last for such a low amount of time. Anyone else have this problem? The ones I used to use with a different setup aren't very common or made anymore. I'm a heavy vaporer. I use just a spinner 2 variable voltage battery. I have tried using the proper voltage with the battery with the atty, etc, but they still burn out really quick.

Can anyone recommend a better atomizer or setup where I don't have to be constantly replacing the attys? At a shop someone showed me a sub-om setup that was really good, but I looked into it and I'm not chasing clouds, I just want a setup I don't have to mess with and change the attys all the time and still get a decent hit off of it. Plus would want to stealth with it sometimes.

Thanks everyone!
