What customers say about "Key Specs"
Polar M200 GPS Running Watch with Wrist-Based Heart Rate
  • First impressions from a first time GPS watch buyer but seasoned endurance athlete. So far this watch has exceeded my expectations. It is comfortable and easy to use.
  • Accurate GPS... I was surprised how accurate it was when running in a forest of 50' tall trees blocking out most light.
  • It's GPS accuracy is amazing and it even picks up my route where I just run on one side of the street vs the other!
  • GPS so occurate, also i like the display - clear and readable.
  • It takes 1-2 minutes for the GPS to lock on... not a deal breaker since I need to warm up anyway but I am used to my phone locking on in seconds.
Polar M400 GPS Smart Sports Watch
  • The GPS work perfectly & quickly & accurately 100% of the time but this device has a large, easy-to-understand, perfectly user-friendly display!!
  • Perfect GPS, very occurate, very stable!
  • I love that display, convinient size and good colors!
  • GPS is a little finicky at times, takes a while to lock into the signal and controls could be better.
  • I always have a GPS finding issues, so frustrated!

What customers say about "Functionality"
Polar M200 GPS Running Watch with Wrist-Based Heart Rate
  • Multiple and adjustable readings during training such as current pace, overall pace, lap and total time, elevation climbed, of course HR,and many more. Such a nice purchase!
  • Good watch for the money. Has most necessary functions. Recommend for all!
  • I love the messaging pairing with my iphone...nice to get the alerts even though you cant see the whole message.
  • Very easy to customize / adjust settings and comes with a surprising number of options.
  • Its have a nice package of functionality, device contain everything i need.
Polar M400 GPS Smart Sports Watch
  • It is pretty cool. It gives you all kinds of info with maps, graphs, and charts.
  • This device records a ton of data and displays all of that data on the screen for you, and it even has a daily diary right on the screen.
  • The best part may be that I can set two interval timers to count down and alarm in continuous cycles, so I don't have to keep stopping and starting them during my run.
  • Like everyone else, I find the beep alerts hard to hear and wish it would vibrate, but I'm glancing down often enough that it isn't much of a problem.
  • The thing that I don't like is that it doesn't vibrate and it's kind of hard to hear it beep when Im running.

What customers say about "Features"
Polar M200 GPS Running Watch with Wrist-Based Heart Rate
  • I was looking for waterproof, ability to change bands (surge lacked in style), GPS, and heart rate. The M200 has all of this and more!
  • My favorite feature is to create training plans.
  • I really like that it warns you when you have been sitting to long. It gives you an inactivity stamp. Really cool motivator to get up.
  • The M200 is a perfect watch. It is simple to use, and the website and APP have a nice 'flow'.
  • Battery lasts barely 3 hours during gps/HR mode, which is really bad even at this price point.
Polar M400 GPS Smart Sports Watch
  • It has full support for the Mac computer, so you can plug it into your Mac, and it will sync to the Polar website.
  • Battery life is fantastic. I have never had trouble charging/syncing this watch.
  • I've been happy with battery life so far, it will generally last for a week of workouts no problem.
  • Battery life is pretty good, good purchase!
  • I have one complaint it's that the battery is only lasting 2-3 days.
