I bought for 75g reef tank for when I go on vacation. Love how I can feed my fish from anywhere in the world and that I can schedule feedings in my phone. Also like that it's plug in so I don't need to worry about batteries.
My only complaint is that I have a rimmed tank and the bracket is not wide enough to fit over the bracket so doesnt get a good grip.
I knocked it into the tank tonight as its not securely held and it floated and still works.
