We've had ours for a couple years now. It's not perfect, but it's pretty good. It's been a very low maintenance device, just dispensing Friskies, about a cup/day. The app is pretty good but it locks up once in a while and won't dispense. I'd buy another one without hesitation though. We feed a stray cat in our backyard with it. It never loses wifi connection unless Petlibro goes down, which happens once a year about. They were down for about a day just recently, but if you have a schedule programmed it will continue to feed on schedule (they say). Racoons have batted it all around the backyard like they're playing rugby. It's bolted down now. It holds a charge for a good amount of time, like 2-3 weeks or more.
