this is a very strong toy for big birds beaks....it will hold up to their strength, after all they can snap a broom handle in half with those large beaks

Pros: strong

Cons: none

These are great to put treats in (in the case of my cockatoo cream cheese and chunky peanut butter, or chicken). They last forever and he never gets tired of it. Its easy for him to hold on to as well.

Pros: Lasts forever

Cons: none

Large birds arent happy if they can destroy something. I stuff paper in them with peanuts. My birds actually destroy them in less than a week. I just have to keep adding stuff in them. Great!

Pros: durable, entertaining, cleans easy

Cons: get bored easy
