Cateye Strada Double Wireless RD400DW

I feel a need to calculate my cycling cadence easily without manual count for 15 second and multiply by 4, so this computer became by latest gadget.
Cateye Strada Double Wireless RD400DW - cyclometer with cadence.

Easy set-up in less than 30 minutes

The cadence and speed sensor working well. My only complain is that the display screen is small compare to my previous Cateye wireless+ and the cadence number is smaller than speed.
