Review on Swinging Perch for Pets by Kathy Babson

Not exactly protection from macaws, but nothing. They last longer than any swing my buzz saw has put in his cage and he loves "swing time". This one is big enough for our BG Macaw to sit on without crushing it. I've found that turning the quick connect upside down and tightening with pliers works better than the right side up - he's a mechanic and easily opens most quick connects in minutes, leaving toys and swings on the floor and they ruin. on the. I order 2 of these.
