Last year the elevation feature stopped working. I can understand that, since it fell off the bike at 25+ mph, and I just plain dropped it a few times. But now, just getting out of the drawer from its winter slumber and the HR isn't working! I changed batteries in the strap, reset the unit several times and still nothing. It cost $99 to exchange last year. I do not want to spend another $99 this year. That will be almost what I can get a new one for. ($99 x 2) Just a little pi$$ed off.
