I got this as a gift for my friend, and he loves it! Easy to use! The perfect watch to get him ready for a marathon!

Mostly Love it so far except that you can't log miles if you run on treadmill. Only have to charge about 2x a month.

I was given this watch as a gift and it is perfect for me. It tracks activity, sleep and my runs. It beeps when I have been sitting for an hour. It syncs to my iPhone. And it tells time!

Works greet. Like how it tracks my activities and let's me know when I have been at rest to long

coming from the Polar Flow Band, this is real professional piece and works very for me. Great is the battery power.

Easy use if first time runner. Nice look big screen

I used the Forerunner 305 before this watch. Aesthetically, this watch has a slimmer fit than the Garmin watch. It also captures GPS a lot faster.

It's the best device I've found, I've tried several others but none compare to this one, The M400 gives you the ability to add sports, and training options something that none are capable of. You can see your speed in mins/mile or miles/hr, avg speed, distance, time, cardio info, time, time of the day, etc. It's good when you're training or when you're in a race where the info displayed is very useful. I'm very happy with it.

This sport activity watch is the best! Simple to use and has great functions on it. Really motivates you to move. Love it.

Have run 4 times with this watch and it has exceeded my expectations, so easy to operate. Definitely would recommend.

I love this watch. The watch holds the capabilities of tracking steps, calories, and daily activity.

My wife gave this to me for Christmas. User friendly.

I feel like this watch challenges me to meet my daily activity goal

I am very happy with this product. It is very easy to use.

I've had the Polar M400 for a little over a month now and I love it. I'm not normally a watch wearer so it took a little while to get used to constantly wearing this, even when I sleep, but now I feel weird without it. At it's simplest, it just a nice watch that can sync to my phone and alert me of texts and calls. At its most complex, I use it to GPS track my runs so I don't have to carry my phone with me. I also use it to track how much movement I get from Basketball/Soccer/Baseball and things like that. The app that comes with the phone is pretty good and easy to follow, but the internet summary is much better and more detailed. It has a step counter and tracks your daily "goal" right on the face, but I don't really use it for that.

No Issues to report. Gps works great and is pretty accurate.

This watch was amazing and very accurate I loved it

Easy to use, fast GPS localization, good training programs. The only feature that is not so good is the speed of synchronization - it takes quite some time to synchronize with my iPhone (6S).

A use this kind of watches to monitor my heart during the biking and running. This is perfect to know my daily activity level with a lot of information including gps
