Love this product! However, the single attachment is not stable enough on it's own to support the weight of a larger parrot.
That said, I solved the problems by using some chunky chains and large links saved from old discarded parrot toys to secure the Java branch at the min point and towards the tip anc created a strong secure stable arrangement which works brilliantly.
It took a couple of days for my YCA Hooch to get used to it but now he seems to love climbing all over it, grabbing, playing and chewing his toys within reach of his beak and he is much more active and seems much happier for it.
