I bought a Hydracoach and I love it!
I was skeptical at first but figured what the hay, I have waisted more money than $30 before that I regreted buying.
I love my Hydracoach! It was simple to program and is very accurate. Now I know exactly how much water I am drinking per day. I liked it so much I bought my best friend one. It makes drinking water fun!
