I too received one as Christmas gift. Compared to my Cateye Strada Wireless (which I loved BTW) this is in a whole other league. It's a really well thought out and nicely designed cyclocomputer. My only problem is with the speed/cadence sensor. It's a bit of a challenge to get both the spoke magnet and the crank magnet close enough to the sensor. While riding outdoors this isn't a problem because I can use GPS to determine speed and can angle the sensor closer to the crank magnet to ensure that cadence is working. However, indoors on my rollers I would like to have both bits of data. Any tips?
