I've been using the polar armband with the visible app for almost a week now. One thing I notice is the battery life seems short. I charged it 100% yesterday now its down to 12%. I may have some setting that uses up the battery since others have not mentioned it. With the garmin it was the 02 sensor that ate up the battery, not sure why mine is doing that
The pulse rate is different than what the watch shows but its fairly close. I move the strap a little bit throughout the day and change arms each day because its not that comfortable. I'm still trying to figure out the pacing points and some other things. If I can solve the battery issue I might keep it. Otherwise no. I only paid for a month so I will decide soon. I'm almost fed up with the watch, I think it just gives us stuff to look at.
the strap told me today I'm overstressed and should take it easy but I'm not sure that is any more accurate than going by how I feel. With the watch, when I feel good the bb is likely to be low 20s or below. A bad feeling day shows the same. Does the polar strap work with other systems? I will probably send it back, for $15 or 20 a month I expect a lot. I kind of wish I had sent the watch back. Maybe I expect too much?
