What do you think of collars with bells on

My little Izzy has a cute little pink, white and black polka dot collar with a tiny little pink bell on it. It was just soooooo cute!!!! Thankfully, she doesn't mind her collar being only 12 weeks old. I like it because I hear the little jingle every time she is running around the house and when I call her and hear it coming towards me, it just makes me smile. I do think the collars with several bells on them would probably be annoying for the cat and for me though!
