Functionality - I love the features of this watch

Charging with standard USB is a great feature as there are many more opportunities to charge versus a proprietary connector

I may switch back to the M400, even though not having to strap on the chest sensor is a nice feature

the M200 is a decent running watch lacking a few features (3/4 line display, auto pause, cadence) that would make it good

Lastly, it also serves as an activity tracker, and it will prompt you with a vibration when it's time to move - cool feature.

That would be a nice feature if it worked but in this case it did not

Great features and nice price

But it doesn’t have a feature when work out begins or ends!

The M200 has all of this and more!My favorite feature is to create training plans

Supposedly the backlight will come on when you turn your wrist to look at the watch (a feature I really like)

I also wasn't aware of the vibration feedback, it is a nice feature

I don't use it for notifications as I've heard this feature isn't great, but I don't really want that

There are some really great features on this watch.

i had a good experience with other Polar gadgets over almost 20 years...also, the wrist-based HRM seemed a neat feature compared to my Polar M400 chest band which often is uncomfortable to wear

Overall a very good fitness watch with nice features

And sometimes...in fact a lot of times I end up just running without GPS...which kind of stinks because for someone who likes the data...it kind of feels like the run "didn't count"...as odd as that sounds
