She has been wrapping up those orders for a solid 8 hours now and still has 7 more orders to go. So yes you got that right! As for the o-rings, I don't really think they will be a problem for quite some time. The PG keeps them pretty nice. You have problems with o-rings when they dry out. I have been using the beta tank for over 7 months now and they are still holding up nicely. Just keep in mind not to over tighten the caps and they will be good to go for a long long time guys....
You are right on point with the O-Rings Vapn!... You will not have issues unless they dry out and become brittle or they are tightened to a point that makes it worn and may cut into the rubber as well. Ofcourse to have a few around won't hurt being the AFS should last a lifetime if taken care of properly~ If its a emergency im sure you can go to a hardware store and find similar working rings. But just like everyone else i would want what's made for it and order from Rob, Lisa.
