Hy to all.
Time to pass to a higher level bike computer. I am interested in qualitative HR monitoring for training sincronized with speed and cadence. As I live in a hilly region with average trip uphill 1000-1500 meters and climbs of up to 35%, I am interested also in a reliable altimeter.
Was thinking about a Polar CS400, but it is a little bit expensive if consider bying all the sensors apart.
As an alternative I want to consider Ciclosport HAC 5. Relatively few reviews, and practically no bad opinions.

Any experience with this device.

To track GPS and to save my trips as GPX files I use my Nokia smartphone with new sports tracker beta, but thinking to buy an external GPS receiver to increase it-s reliability.
