My vet must buy from this company, because my bird had the same collar. My main issue with it is that he figured out the Velcro fastener pretty quickly, he bites at the collar until he spins it to where the Velcro is in front and then he starts chewing at that, as soon as the opening is big enough, he slips right out of it. The vet said to put some packing tape over the Velcro part, and that sort of works, but now he is just chewing at the tape. A better design would be just over the head.
