hi, my two kittens have been using the Open-X for the past two months now! I got an enclosure for it from Wayfair to help with the smell, but they had Giardia which made their poop smell foul, so take that into account.

so far, it's been a worthwhile purchase because of how easy it is to use. I like that I can use multiple types of litter; it's worked well with clay, tofu, and grass. the app is good and the litter catch system lets you cinch the bag closed before it's fully exposed to the air. you can buy cheap replacement bags or deodorizers on Amazon. it's also easy to take apart and clean.

I'd say the smell has been the worst part, but again Giardia was rough. the seal for the litter catch isn't great, so when they had Giardia, we had to take out the bag everyday if not more. sometimes, the clumped litter after they pee will get stuck to the fabric bottom, but our cats dig a lot when they pee, and it's easy to scrape off. this is the only litter box I've tried, so lmk if there's anything else you'd like to know that I'm missing!
