suppose to be waterproof.First triathlon watch stopped when I exited the water.

The last reviewer said he had problems reseting, this is true, the first time I had to replace the battery I had problems. But instead of sending watch in to be linked, I called customer service, like most people would do, and they promptly walked me through the correct procedure. I love this watch, but I agree that battery life is a little less than I would have liked. oh well, great product overall.

Customer Service

Great customer service! no problems at all helping me link the HRM to the watch.

Do not buy this product! This would be a great product if you didn't have to reset the battery 1X/year. You are supposed to be able to reset the "link" between watch and heart rate monitor from home, but each time the battery went, I had to send it back for them to "professionaly" reset transmitter. Not only does this cost around $20 after fee and shipping costs, but you are w/o the watch and transmitter belt for 2-3 weeks. I hate the fact that they lie about being able to do it yourself. My advice is to find another product that is easy to reset.
