Got this cheap at my LBS (they were unloading them from another LBS that went under). Not worth the $15 I spent let alone the normal MSRP. I have the sensor and head unit within the normal operating distance (granted it is on the outer limit of that) but it never works in temps less than 45 degrees...and works intermittently at best the rest of the time. When it works...it does the basic job I need it to do...which is to track ride time so I know maintenance schedule milestones. Doesn't work enough for me to even do that though. Often time just stops taking readings mid-ride. Have Cateye micro's on all my other bikes...will probably switch to that at some point soon.
