I had a full size one and it worked fine for my sheep (not horned but there's nothing for them to catch horns on). There was a bit of wastage, but sheep waste hay anyway. It was great to put out a big bale and not have to worry about it for ages. It IS easy to move, although the shape means it doesn't roll in a straight line - great if your DON'T want it to move far but a PITA if you do. And it does protect the hay.
