The yellow connector fit perfectly between the bars, and it was very easy to put on, no bending of the cage. My girls are still getting used to it, but i have seen a couple of them use it and it makes no noise whatsoever. They might use it at night when they are most active but i don't here them. It is very easy to remove also. You just have to unscrew the nob and it pops right off. I would definitely recommend it!
