Bests & Worsts Reviews from Amazon

Bought this to track my HR on Strava. It worked great for about 3 rides. Now it will not pair with my phone. Washed the strap, changed the batteries, reset bluetooth, reset application, restarted phone, tried to pair on three other phones. No luck. Will see if they will take it back. Update: A comment on another review mentioned that shorting out the battery connectors for a few seconds reset the unit. I tried that with a paper clip and my unit is up and running! Strava is able to measure my HR and shows that the unit is connected but there is no paired device listed in the bluetooth settings. Shame on Polar for not mentioning this in its trouble shooting guide. Full disclosure: User Mark Love made a comment on one of the two star reviews on the battery shortage solution. http://www.amazon.com/gp/pdp/profile/A1OO7FYQ3Z0JO7/ref=cm_cr_rev_detpdp
