POLARPacer Ultra-Light GPS Fitness Tracker Smartwatch for Runners; S-L, for Men or Women, Black

nice watch

used primarily as a heart rate monitor. Works great alone and when linked to Polar H10 sensor. Excellent detail when linked to Polar Flow app Tracks many different types of workouts in great detail as well as providing accurate sleep analysis. Good value for cost.

This is great is light and thin, love it, I did not wanted a big one like the ones everyone has, I barely feel it. Great battery live

In about four months, the light started coming on during workouts when the device was set to backlight on button press only. It would take two button presses to turn it off (It should only take one, indicating a malfunction), and it usually came right back on after shutting it off. The light was just almost always on during workouts no matter what. I filled out an online form and sent it in for repair, paying shipping and making a trip to the post office. When I got it back two weeks later and started a workout, the light came on instantly. Apparently it wasn't even inspected. Adding insult to injury, the returned return contained an invoice for another customer, but not my invoice. I sent them two emails about this and haven't received a response (It's been 8 days since first email and 2 since second).Update: Sent it for repair a second time, and the main body was replaced, or at least the plastic case which has a new serial number. It had exactly the same problem which started immediately. Without any help from Polar I thought it might be a firmware problem and updated to version 2.0.12 with FlowSync on a PC, and the problem is completely solved.

I ride my bike often and wanted a monitor that isn't a chest strap. This watch picks up my heart rate very easily and works very well. It has tons of features that I don't use but that's fine, I use it just when I ride. My only complaint is that I have to pair it with my phone literally every time I ride. This is very annoying. I use run keeper on my phone that is mounted to my bars and I like to have the current heart rate on the display. The watch collects lots of data, average, peak etc. and I'll look at that when I get back, I just want to see the current on my phone display. I use tons of blue tooth devices and the only one I have to pair every time I use it is this one. Wish some smart engineer could fix that one issue. Other than that it's a nice product and worth the price.

As an athlete and soldier in the Army, i find this pacer to be amazing alongside polars chest heart rate monitor. It really helps me correlate my heart rate to my rate of exertion. I was an off and on runner before but now im trying to drop my 2 mile time and prepare for marathons and these two polar products are definitely helping me get that mind body connection that i was originally only used to from weight lifting.

Exelente,me llegó en perfecto estado

The battery lasts a little over 3 days hiking 12+ hrs a day which is why I bought this one. If you wear the H10 chest strap HR monitor this watch will automatically use that rather than the optical monitor as the H10 is more accurate.EDIT: I gave it a 5 star review but the HR accuracy is not accurate for the first mile or so and intermittently inaccurate but I have a Polar H10 chest strap which is very accurate. Example . . . Ive been wearing it all morning and when I turned on an activity (other outdoor activity) it read my HR was 60 so I put on the H10 chest strap and it immediately read 115 which was accurate . . . I was digging up plants out of the garden and was curious how many calories garden work burned.This is probably true with all optical wrist HR monitors
