I bought these after my husband had a bout of dehydration and developed a UTI. He's like most people who just seem to forget to stay hydrated. I can fill them up with various liquids, water, sports drinks, juices, etc. and make sure he's drinking enough 8 ounce bottles daily to gain at least 56 ounces. This is in addition to everything else he drinks. They are easy to clean as the mouth is big enough for a baby bottle brush and is upside down to drain the water. They're not flimsy plastic like some of the others we've tried, so they're durable and can handle very hot water. The only criticism is the lid. Sometimes they're hard to put on and some I just can't get the little ring off so they don't move sideways.
