I like it a lot more than regular hay feeders because the hay stays in it. Before a lot of hay is wasted because it lands on the bottom of the cage and then spills over everything. My guinea pigs don't bite it either. I wish there was a metal ring around the whole thing instead of just the front. If it's not screwed tight, the pigs will end up tipping it over, and that's how it's going to end if you don't fix it.
