Got my Cartomator yesterday... Works great, looks great, everything fits nice and snug!
My main concern/criticism with the Cartomator isn't the tank itself, it's the holes in the carto. They are nice and clean, at 6 and 12, but they are WAY too high! The carto that came in my tank has the holes drilled right in the middle of the carto! Once my liquid level gets down to the hole (halfway) I will have to fill up again, rendering the liquid in the bottom of my tank useless.
The holes need to be drilled just barely above the delrin, so you can actually get down to the bottom of the tank before you need to fill up. That is the ONE thing that the Liquinator has over the Cartomator, their slots are just barely above the delrin cap, making full use of the tank.
If you guys can get the holes in the carto in the right spot, you will have surpassed the Liquinator on all levels. Until I know that bug has been fixed, I will be putting ugly slotted cartos in the Cartomator, which cuts into your profit!
Other than that, awesome product!
