Took me about a week to find the switch to activate it. I was pushing the button but I couldn't find the switch on the battery. I finally found it and it works so well. My mom loves it on the her pup
Was very cute. Lit up well. Lasted 4 uses. The wires are so thin it somehow broke off. I don't like how it bunches up on my dog. I did purchase the appropriate size. You have to keep straightening it so people can see the design and lights. The inside is a silky material. $17 wasted.
