Been using Smart Water for about five years on and off ever since it came out. You know every once in a while you're, you're in the grocery store, you're like, I need a little boost. Not going to go for that Poland Springs, not going to go for that tap, and not going to go for that smart water. Gotta say over the last five years, they've been good years. Not sure how much of that is attributable to using Smart Water about once a month. Maybe a little less than once a month, you know a couple of times a year. But, certainly correlated with you know having a nice time overall.
