Bests & Worsts Reviews from Amazon

I bought this after reading the glowing reviews on Amazon. I thought it was great for the first week or so, no more scooping, yay! Then, the negatives started showing. - The regular size box is too small for my 13 pound cat. (So for those who want to get this box, I recommend the Large size.) - The clips, though they didn't break off on me, weren't very secure and are very flimsy. I always had to double check to make sure they were secure before rolling after a couple of accidents where half the cat box contents spilled all over the floor. - Even when the clips were secure, litter would leak out on the side mid-roll. As a result, I'd always have to vacuum every time I tried to clean the box (twice a day). - Clumps often got stuck on the grill, and they were difficult to get off. Cleaning the box is a nightmare. I had to disassemble, scrub the top (sometimes there was dried poop stuck to the top because of the rolling action), then really scrub the grill thoroughly (took forever due to stuck clumps), scrub the pan (and the spots where the grill inserts into the pan almost always had litter I couldn't get out because of clumps there)...every time I washed the box, it took me a good half hour to 45 minutes to get it completely clean, dry, and odor free. - While the rolling action is great, the smaller clumps go right through the grill. I still have to take off the lid every three days to manually scoop out the smaller clumps. - Didn't contain smells. Two weeks after a thorough cleaning, the box smelled terrible, probably because of the dried poop stuck to the top. I went back to a regular scooping box with a lid, and after my experience with Omega Paw Roll n Clean, it's been a dream. No more litter all over the floors, no more vacuuming twice a day, no more spilling litter all over my foot whenever I try to clean the cat box, and no more wasted litter.
