POLAR Vantage M –Advanced Running & Multisport Watch with GPS and Wrist-Based Heart Rate (Lightweight Design & Latest Technology), White, Small

As an avid trail and road runner (running 80-100 mi/week), I cannot review this watch highly enough. Having trained in a variety of watches over the years (Garmin, Suunto, Epson, and Polar), this watch is by far the best. The battery lasts forever before recharge, it is easy to figure out how to use, and it has all of the relevant features (HR, current pace, average pace, POWER!!!, splits, elevation, etc). As a trail runner, the new power metric has been extremely valuable since it is the only metric that remains constant through hills (HR goes up, pace goes down, power stays the same). Moreover, the watch is comfortable enough to sleep in, and is sleek enough to wear to work in a professional environment! I really have no critiques at this point and would recommend to anyone looking for a performance-oriented, good-looking, comfortable watch.

So far I like it. It does a great job recording and logging my activities (you need to pick one before you start).

I love the bigger watch face and long battery life. I don’t have to charge this for weeks even with lots of use! The buttons do take some getting used to and there isn’t a touch screen but I love the price point of this watch and it’s definitely a great workout watch!

I used this to track sleep, run, bike, swimming and weight training. Running on treadmill or outside is OK. but the heart rate sensor is completely unreliable for other activities. I tried on both wrists, different positions, different tension, it's still hit or miss. >50% of the time it won't track my heart rate. Maybe because I'm a woman with small blood vessels? do other women have this issue too? Sleeping tracking is interesting but I found the rating is not correlated the quality of my sleep. On low rating days I could feel really rested, and after bad nights it could give me a good rating. So overall it's pretty useless. I'm looking to get rid of this and get another brand.

Polar muy bueno solo es pulso es muy corto

Overall, i really like this heart rate monitor, the only flaw is that it does not track my heart rate correctly 100% of the time. I bought it to replace a very very very old Garmin. I think the ability to wear it 24/7 and track your activity + sleep is 'fun', but not why I bought it. I just needed to track my workouts and heart rate.Some Pros: I think it is a good looking watch. The interface is easy to use, and I love all the sport profiles that are available. My favorite thing so far has been the ability to buy this in a small. I have very small wrists, and it's a luxury to be able to get it tight enough with out a long tail on the wrist band.Cons: My only con is that it does not track my heart rate correctly for all sports. It works just fine for weight training, pilates and indoor cycling. But when I wear it to walk or do the elliptical it is wildly inaccurate. Based on reading another review, I think it has trouble reading it correctly when I have a lot of arm movement. Therefore, I will be buying a strap to monitor my HR during these activities. Admittedly, it would have been convenient if the HR tracking via my wrist worked 100% of the time. But I was skeptical about this from the beginning, so I'm not shocked there are issues.

Battery last forever, also recognises different swim styles.It’s more accurate than the M430

Love everything super specific with swimming which I mainly what I do ... Highly recommend
