Smart Little Thing
I thought I was being ridiculous when I ordered this.  In the first week I've been using it, I've averaged about 100 ounces of water a day.  I was struggling to make it to 64 and failed most days.  I would say this was a great investment.  I followed the advice of others and bought some of the round Velcro stickies and stuck one on the Ulla and the other portion on my different water cups so I don't have to worry about losing it!  So far I haven't even come close, it doesn't move!
