I'm not surprised. I don't think the build quality stands up to the complexity of the mechanism. That's why I'm interested in the new model, which is basically a bag with a removable pinch at the top.

You're right, but I think it essentially uses gravity to pull more of the bag out. The first model uses the turning mechanism to mechanically pull more of the bag out. This one, as far as I can tell, just does it with gravity. I'm surprised they designed it this way, frankly, as it seems a lot more efficient, resulting in less income on refills for the litter locker company smile
