I received this is product in exchange for my honest review, so in my honest opinion these are great straws they are very sturdy and don't. They are very easy to clean it came with two cleaning brushes so cleaning is even easier, i really like the fact that i have both straight and bent straws. We use them for our RTIC cups and they work perfect for them so i'm sure they would work great for you yeti ozark etc...these are well worth the money and would recommend them to anyone   BUY NOW!
