Title: Do not buy this product
Review: I've had this unit for a couple of years, and haven been really disappointed with it. The heart rate monitor is really erratic. Even though I live in a rural area (Santa Fe, NM), stray signals (from who knows what in this sparcely populated area)through the heart rate monitor off. The batteries in the cadence sensor and the heart rate sensor have to be replaced about once a year. Even worse, when the battery in the speed sensor is drained, you have to buy a whole new sensor. My speed sensor battery died in about two years. The cheapest price I've found for a new speed sensor is about $35.00, before shipping. I've decided to spend that $35.00 on another heart rate monitor. It will not be a Polar.
