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

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.

Overall i think this is a good watch. It has A LOT of information for your fitness. I returned this item shortly after buy it because (1) the watch face is not very customizable, and (2) the screen is quite small for such a big watch, and (3) annoying to go into "activities" menu to see my step count. Because the watch face is not customizable, it gets annoying to go into "activities" menu every time when I want to see my steps. Again, nothing wrong with the watch. It's more of a personality thing for me. Also, I didn't need all the information that it provides, thus I went for a cheaper option.

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.

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.

This is a pretty basic fitness watch. The step counter is fairly accurate and it's a pretty good price. It's light on the wrist and doesn't stop me from sleeping. Pretty good companion app for Android.

I had a Polar M430 for years that finally broke and no replacement was available. I was beside myself as I had loved the watch so much. Finally broke down and purchased the Pacer and j am over the moo ! Lightweight, so easy to use, holds a charge for days and provides more than you could ever need in a running/fitness watch. Look no further...this is the watch you NEED!

This is a great watch. Gives me HR, pace, distance and total time and it's very accurate in each of those areas. It also gives me a ton of stuff I don't need but maybe others do, so I guess that's okay. The only thing is, it can be complicated to figure out how to do things quickly because there's a bit to remember even just to do the basics (I'm old, it's difficult :) ).I do have one comment related to something I've seen in other reviews. Several people have said the watch screen is hard to see, that it's too dark. If you play with the menu long enough you will find two different sections for screen brightness. One is for the brightness itself and you can set it at low, medium, or high. There's another menu where you can tell the watch to leave the screen brightness on permanently. When you do those two things, the screen is very easy to see, even in cloudy weather.All in all, a very good watch. I'm glad I bought it. The added ability of syncing with a 'diary' on the Polar Flow site to keep track of EVERYTHING is a great added bonus. I've even found out I'm sleeping good :)
