I have 2 green cheek conures (male and female). My female "Sophie" LOVES this chewy toy!! It's my 5th or 6th repeat purchase of the medium size one. Initially I was buying the small size but she tore through it too soon and the large one was enormous and I had a hard time putting it inside her cage when she goes to sleep at night. The medium size is great for her, as she loves to pull ONE crinkly paper out at a time, and walk over to the corner of the "roof" of her cage to chew it and press it until it's nothing but a teeny little "ball" of a piece of paper. The medium one lasts me long enough so I don't have to repurchase as often, and I love seeing her enjoying herself with this very simple but mentally stimulating chewing toy! The only reason I took off a start was because the netting that holds it together has to be thrown away when she's finishing it off because these tiny fibers are worrisome for my Sophie to be chewing on (she will!) after she's finished all the crinkly papers. But I save the silver hooks for other toys I can hang, so that's another little plus to this toy!
Also, I took a couple pictures of her chewing it, along with a video showing how she does it, but unfortunately I couldn't find a way to upload anything on my review for this product.
