I liked it so much that I became addicted on saving heart rate performance for analysis and so purchase a lighter than iphone dedicated GPS watch to use with the Wahoo strap. Now I don't use this so much, but the product is very good.
Its cheaper than a fully loaded GPS/HRM watch but for racing I'm affraid of trashing the phone. For a not so intese use is perfect or indoor gym use is perfect.
