I've been using it for 2 months now and I'm delighted! The only downside is that there's no odor filter 😔 I have 2 cats, one weighs 2kg, and the sensors work well.
It arrived in Spain in 10 days, I have 3 cats and all 3 have been using it from the beginning, it's wonderful. I program it to clean every time the cat comes out or every few minutes after the cat comes out. The app is in English but it's super intuitive and easy to use.
The communication and dealing with the seller has also been excellent; I had a small problem that the seller resolved immediately, giving me options and different solutions. Both the sandbox and the seller are worth it; the seller is completely trustworthy, and sometimes these extra valuable things give you peace of mind just in case. . . . . Well, with all confidence, I don't give it more stars because it's not possible. My cats are happy and I'm even happier because I save myself from daily cleaning.
good
Works great. Arrived quickly.
