As much as I despise cleaning litter boxes, I wouldn't waste money on these on a regular basis. However, if you're traveling with your cat these liter boxes are great. Cleanup is easy since you just throw away the box when it's time.
I purchased this litter box for my cat and neither of us liked it. First off, it didn't seal right, so my high spraying cat got pee everywhere. She also did't like the grate for her paws. I ended up taking that out. The litter box scoop was also small and flimsy. I bought this litter box 5 years ago so maybe the quality improved.
This litter box does a great job keeping both litter and odors in. However, the lid isn't very secure. One of my cats is a high sprayer so if the box wasn't sealed correctly in back, she would get pee everywhere.
This carrier is amazing! The price is comparable to most plastic carriers, if not slightly more. One of my cats gets distressed when traveling. He will claw at the metal gate on the hard carriers, and ripped out a claw doing so. With this carrier he can move more freely, and I don't need to worry about him damaging his claws.
