The best five-dollar bottle I’ve ever paid for. I’ve been using mine for three years. This bottle holds 64 ounces. I love that it has markers on it with motivational quotes. I use mine daily, sometimes to drink strictly out of, and sometimes keep track as I pour into other glasses. I keep one in the fridge for my son to pour into his water bottles. He wants to use it for the day or his cups so I can track how much he drinks. One rule our family keeps is if we’re not on our Mark, we can’t have something else to drink, so for example, when 5 PM comes around, we’re having dinner. I want a glass of wine. My son wants a glass of soda, but we haven’t drunk up to the 5 PM mark on our water bottles, so we can’t have a different drink. We need to drink more water. Sam has said to me that they can’t handle bottles that are insulated, but I, as an ice lover, don’t mind this bottle one bit in the morning. I fill it up to the top with ice, and by evening, my water is still fantastic. You can always add more ice, but it’s a great tracker if you’re trying to keep track of your water.
