I have tried putting it in the following places:
inside a cage, stretched from side to side, hanging down from the main mirror on the wall, on top of a cage, across the front of a cage, hanging down the front of a cage.
It's been mostly ignored and feared.
The closest they have got so far to it is Lilek biting some of the blue plastic chains when I have dangled them in front of him.
They can be such scardy birds at times. If I was a budgie (which I am not, I think) I would love this toy!
The contrived tree rends a healthy workload.
