User Reviews about Polar RS100 Heart Rate Monitor and Stopwatch

This heart rate monitor was easy to use, once I read the manual and figured out how to set it.

However, I've used it on a couple of bike rides since I got it last week. Today, I biked 17.5 miles in just under 2 hours. Four different web site calorie calculators gave me calories-burned numbers of 879, 986 (2), and 994, based on my weight. The Polar RS100 gave me a number of 569. That seems abnormally low to me. A similar thing happened last time; the Polar was quite far below the websites.

This is disappointing, as I bought this primarily to show calories burned during exercise. -- Disappointing calorie calculation
I was using a timex monitor that I got for cheap at Costco. It wouldn't work with the precor machines and I kept losing the signal. My trainer recomended buying a polar and replacing it and glad I did.

I get a reading as soon as I put on the strapband (with my timex sometimes there was a almost a minute delay before getting a reading even using heart rate cream on the strap). It works fine with all the precor machines and it is nice having the reading go on the machine and getting told the heartrate stats as well when I finish an eliptical machine work out.

There is one thing I dont like and I may just need to read up on it. I can't figure out how to get the time to show with the heartbeat. I also like to time some things and the only way I can figure out how to do it is with the lap feature. Not a big deal but I have the alarm sound turned to silent but it wsill still beep when I am outside my targeted heart rates which is annoying and embarrasing at a gym.

If someone wants a cheaper heart rate monitor go with this one. I wouldn't recomend any of the other ones that sell for cheaper like the timex, they don't work with the cardio machines and this does, and this one is also reliable. -- Great monitor for basic use and with cardio machines
This is my first HRM so there was a learning curve on using the features of the product. I'm typically pretty good with electronics and functions/menus. For some reason it has taken me a little longer to get this one figured out. That said it works great, really helps me focus on the performance level of my workouts, I should have had one years ago. The workout summary is great and helps me track my progress. It took awhile to get used to the chest strap, it is not uncomfortable, but was different having a strap around my chest. -- Great product
