Let me start off by saying I love this cup. The only thing I didn't like was the color of the green. It's dull. Reminds me of pea soup. My sons team colors are yellow, green & black so I was disappointed when the green wasn't vibrant. I ended up buy a black one to interchange the colors hoping it would help but not really.
Our girls volleyball team were beaming ear to ear when they realized we were blowing our loud cups every time they scored! These are amazing! I keep it in the car for every occasion! They are durable, easy to clean and perfect for showing off our team spirit! P.S. if you take it apart, it becomes even LOUDER!!!!!
I bought a cup to bring to my great-grandson's all-star games. At the end of the game which they won I blew my cup and shocked everyone, After that everyone wanted one, I purchased more cups for my granddaughter and one for my grandson who is a teacher, he wanted it for his classroom.
