Bests & Worsts Reviews from Amazon

I was so excited for these. I’ve been looking for a sturdy, easy to use, easy to clean, replacement for slippy cups. I tried them for a few weeks and ordered a couple more packs. BUT now, I’m frustrated. There’s a serious design flaw. The magic ring of the straw that keeps them from pulling it out is not a solid ring. All of my straws, however it’s made, are left with the tiniest hole. I only see it because mine drink chocolate milk often. No matter how I wash, I cannot get the chocolate out. Today it’s chocolate, tomorrow it will be molded. The search continues. These were not cheap. Very disappointed.
