Works perfectly for what it does. I was hoping to be able to change some mason jars to glass sippy cups for my toddler, to avoid the plastics. The problem with this is if he leaves it on its side it spills everywhere. So doesn't work well for my intended use...should have a spill resistant seal that as you suck allows fluid to flow through, but not if it is on it's side.
