My husband that absolutely refuses to go Apple loves this thing! It's also really big I can't imagine a woman wearing it. The profile is very large. My husband can't wear it to sleep in like he did his fit bit.

Great little android wear. Pros and cons (in my opinion): Pros - Nice, clear and vibrant display. - Works with swimming. - Unit is removable from strap, and it can be changed out and cleaned properly. - Polar has a great app that syncs with other things like Strave, useful.

Excellent device. The band is soft and comfortable for all day use. Using with iOS. Short battery life requires nightly charging. Ok once you get in the habit. Features are excellent and the HR monitor works much better than other wrist base devices for tracking sport performance.

Though the watch seems to be working for now, I am a bit wary of it. Upon opening the outer shipping box I found the inner box ripped on all sides of the clear plastic cover, that displays the watch in the store, where it had been ripped off of the box and the watch seemingly having been removed and...

Overall, the Polar M600 looks and behaves more like a smartwatch and less like a running watch. The integration with Android Wear is slick, and Polar Flow is a clean and easy-to-use app, but the watch falls short of expectations once you start running.

Smartwatch notifications; Accurate GPS; heart rate monitor; Easy-to-use Polar Flow app

Bulky; Disappointing activity features; Short battery life

Whether you're working off last night's takeaway, trying to outrun middle age on a treadmill, or lifting weights in front of a mirror like a preening peacock, you're basically just a sweaty mess.

As a comprehensive fitness tracker, the M600 is pretty well equipped. You’re still not guaranteed to find GPS and heart rate tracking in other Android Wear watches, so if you can put up with the mundane looks, it has a slight edge for recording your exercise routines. With an ever-increasing app library, too, there should be something here for pretty much every activity or sport. Android Wear notifications and second screen smartphone controls are handy to have, but only if you’re going to be wearing your watch all the time. I’m not sure this fits the bill for something you’d wear every day, though. The design and build make me think this just isn’t meant to be worn outside of the gym. Seeing as it’s kind of pricey, too, I think you’re either better off with a dedicated fitness tracker like a Garmin Vivoactive HR, or saving a bit more cash and going for an Android Wear watch you’ll actually put on every day.

If you're in the market for an excellent running watch with a heart rate monitor that also counts steps and has some smartwatch capabilities, the Polar A360 and the Garmin Vivoactive HR are much better options.

High-quality build; Built-in optical heart rate monitor; Runs modified version of Android Wear; Waterproof; Works with both Android and iOS devices

Bulky; Short battery life; Occasionally high heart rate readings in testing; Can't set a custom activity goal

Bought this instead of a Samsung Gear Fit2 Pro, where the GPS barely works ... What a difference ... GPS locks fast, the statistics seem to be fine. Polar's "Flow" app and website provide a good overview of the training. It uses it as a lock-in, and it does it with a goodbye.
