Had been the Litter Locker II in use and was up on the high-priced refills very satisfied. Since my household now enlarged to 2 cats, I wanted to try bucket with much größerten Swirl. First of all on me much negative that it offered no refills (only via other providers and with postage costs), which of course I wanted the same to order. Got me the bags so otherwise. The litter collector arrived and was immediately tested once. A door was loose in box, was quite difficult to assemble. Once the suspended bag is filled to 1/3, the valve closes completely and no longer stinks pathetic! Idea would be good in and of itself, execution works, however very insufficient. Was returned!
