I saw this at my Mom stroller-fitness class and had to have it. It's a great product that not only motivates me, but seems to motivate the other moms around me, too! It was easy to install on the inside of my wheel and there's a great "cheat sheet" for my Phil & Teds that I got off the Strollometer website. The features are cool, but what makes me feel really good is looking at the total distance I strolled during the day. I recommend it to anyone with a stroller!
