We used to buy our water from the grocery store. After meeting "Dan the Water Man" and talking about the differences between that and his purified water, we decided to give it a try. Now, my 12-year-old son drinks more water, has had noticeably less headaches and I save money!!! We use the water to drink 24/7, cook with, and fill up for workouts ~ And it is delivered! This truly is the best decision we have ever made.
