My huge ragdoll cat has been using this litter box for 4 years now. I absolutely love it.   I do have to scoop it once a week but it’s no problem. I save $ by purchasing the bags of crystals. I bought an extra tray, so when I change it (about every 3 weeks), I just get the extra clean tray out. I wash the dirty one and let it dry for next time. I also put a good amount of baking soda on the bottom of the tray before adding the crystals. Because my cat doesn’t like scents, I use the sensitive litter. Adding the baking soda keeps the odors out. We used to have 2 cats and this tray accommodates 2 fine. I am 70 years old & have spinal & neck fusions. Life is so much easier with this tray.
