This is a great grit feeder, larger than I expected but plenty of room to fill it up and it stays dry. Only problem I have had is getting the roof to stay on, it keeps popping off. It takes some fiddling to line it up correctly to get it to stay on.
We bought this for our 4 girls and our Cube. It holds a lot fo grit and is easy for the girls to use. However it seemed a bit big.
Very pleased with this, much bigger than i thought it would be! Will be purchasing another one for my bantams.
