I was leery that my cat would be afraid of this because he's afraid of everything but he took right to it. The set up took only minutes and the app is really easy to install and use. There are lots of settings to suit whatever feeding schedule you want your animals on and allows you to feed instantly as well. It even seemed to work when our wifi went out for a day. I'm really pleased with it and it's made for a lot less howling and hollering when he can see the bottom of the bowl. A quick press and he has a snack to soothe the savage beast. It fits well where our regular bowls were and it operates quietly so it doesn't startle him. Overall I'm extremely pleased and so is my neurotic cat! 10/10 will definitely use again and again.
