Strengths: Easy to install and set up. Inexpensive @ 40$ for wireless cadence.
Weaknesses: Other than I had to replace battery right out of the box, nothing really.
Bottom Line:
This review is for the Serfas Si-3 wireless cadence. It's basic, inexpensive, easy to install. Good accurate readings, even after I purpously tried to mess with signals (Used my Polar directly beside it). Cadance battery was complety dead.
