Out of the box, plastic is slightly broken (see photo). It doesn’t affect functionality, but it’s annoying for something so expensive to arrive damaged. Some of the physical buttons are not available on the app (“R” button), so if I forget to reset the weight after adding litter, or activate it after a power outage while I’m not home, someone will have to physically go push the button. It’s a tight squeeze for our 10 and 13 lb cats, and they often poo down the side wall instead of into the box.
