Ok I can actually do a mini review on it now. I got the glass and have been using it all day. First, it cannot be used on anything but a Zenesis 2 or Sidewinder. I would hope that Zen would make an adapter so you can put it on other devices. There are orings on both caps and they appear to be similar to orings used on other tanks. However, you screw the carto into a gasket on the bottom cap so you don't have to worry about the carto damaging the orings. There are 4 air holes in the bottom cap that allow air in so the carto can breathe. Zen made a video about filling the tank. You have to put the top cap on, but not all the way, and turn it upside down. Then you can push the top cap in and turn it right-side up. This is done so the carto does not flood.
I'm actually pretty disappointed in the device. The first thing I want to say is that it does produce good flavor. I'd say that it's one of the better flavor producing carto tanks. However, the way the tank design requires you to pull pretty hard to get vapor. When you put a kick in it the top does not screw on completely. Though I understand that it has to be like this in order for the device to fire, I do no understand why an oring was not included to cover the gap that it causes. Many people say that it won't fire in 18350 mode. An additional washer is required in the switch. I believe that that should have been included as well. The glass is quartz so it is very weak. I would not take this out of the house without the SS tank, which costs extra. I give the complete device a 5.5/10. You pay $200 for a mod it should, at the very least, come with everything you need to make it work properly. Also, I feel for that amount the glass should be pyrex.
I'm running the 650 carto tank with a 18490 and a kick. When I first got it I was disappointed because the tank kept leaking out of the air holes. Then I found out the "special" way that you have to fill the tank. It definitely produces the best flavor of any carto tank that I've tried. My caps screw on just fine with my battery and kick... I'd say my biggest complaint is that the tank is very fragile.
