Well, this is a pretty different use and experience than a carto tank. You can use any 510 atomizer, essentially, without the need to modify them. You just prime it up, toss it in the tank, and off you go.
The trick w/ the AMP tank is getting liquid into the atomizer. You have two options:
1. Manual feed - this uses the carburetor hole in conjunction with an inhale w/o firing to get liquid into the cup
2. Auto feed - This uses a vacuum seal along with precise opening of the atomizer in the connector to give you the right amount of liquid into the atomizer to keep up with your vaping style/wattage output
Either method has you pulling juice into the atomizer via the air intakes around the 510 connector of the atomizer, rather than a punched hole like on a cartomizer. Also, unlike a cartomizer you can flood the atty by getting too much juice. When that occurs, one of two things will happen:
1. You get juice in your mouth while taking a drag
2. Juice leaks out of the center post of the atomizer through the carburettor hole
It takes some practice and effort to get yourself auto-feeding with consistency...but once you do...it's freaking fantastic.
