And the watch started out great, with useful and fun features. But all the features in the world are useless if it doesn't do one fundamental thing right: Be a dependable stopwatch:
I went out on a 20 miler 2 weeks after getting the watch, and at about 10 miles in, I look at the watch and it says: "Something went wrong. Press OK to reset M400." ('Something went wrong' being an unintentionally comical understatement.) After pressing the OK button, the watch restarted -- with the entire previous 10 miles wiped
If you're in training, you know this kind of thing is important. SUPER frustrating.
But it was just one glitch, probably a fluke, right? I sent the watch back for an exchange to Amazon, and got a brand new one. And now I could get on with my life and everything would be fine. Until this morning, when out for a run and the watch crapped out the EXACT SAME WAY. ("Something went wrong.") Heartbreaking.
2 watches, 2 total system failures, 4 weeks of ownership. I can't go through this again. I'm done with the Polar M400. (Back to my old Timex Ironman, which still works the same as the day I got it.) Maybe my experience is atypical, but i'm getting down on record for your benefit, runner-who-is-thinking-of-buying-this. Be careful.
PS. Sent an email to Polar customer service and received their response before writing this review. I described the situation the same way that I have above, and their response was essentially a perfunctory apology and a request to send the watch to them for warranty repair/replacement. Not a wholly unreasonable response, but not one that convinced me to continue with their product. At all. It's going back to Amazon for a full refund.
**UPDATE #1**: I wrote the above review within hours after the second M400 crashed, and I'm not sure if you can tell, but I was pretty upset. I ended up immediately sending the Polar back and ordering a Garmin Forerunner 10 to replace it. And after a couple of days with the Garmin, as much as I hate to admit it, the M400 spoiled me. In comparison, the Garmin seemed clunky and inconvenient. I just didn't like it.
So after going back over the reviews at various websites, and after some deep ruminations, I've decided to give Polar one last try. Hopefully this is a case of "Third time's the charm" and not "Fool me once, shame on you, fool me twice shame on me, fool me three times, and I've got to be some kind of world-class idiot." Depending on how things go, I'll revise this review.
The watch displays standard watch functions like day, date, timers, time, and alternatively if I choose it will display a set of exercise metrics according to choices I made at the Polar Flow web site. Each time you sync the watch to the PolarSync app on your PC, the app automatically uploads the watch data to the PolarFlow web site where it is processed for user viewing and analysis in various ways, You get some really nice tracking information in the form of a map of your route, graphical charts, comparisons, suggestions, and even a video that incorporates Google Earth (it seems) to show key points along your workout route, complete with background music!
Build quality seems nice; the watch is waterproof and its strap is sturdy enough that you don't have to worry about losing the watch. By necessity, the watch display is big enough to present you with a large readable display of exercise metrics the watch has collected.
The Polar M400 used in conjunction with the Polar H7, the PolarSync app, and PolarFlow web page, make for what, it seems to this reviewer, a complete package. Even so, I left a star for improvement in the area of auto-detection of activity like walking, gym workout, treadmill, etc., and reliability has yet to be determined.
A recent negative experience with the H7 Bluetooth sensor left me feeling much more negative about the M400/H7 combo. It missed a few beats over the course of a few days so I became suspicious of the 3-month old battery. But after putting in a new CR2025, it wouldn’t pair with the M400 watch so I followed troubleshooting guidelines and removed any evidence of previous paring by deleting the H7 from the list of paired devices and then tried to pair again. I tried “Pair and sync mobile device” to no avail and then “Pair other device” with the same result. Also I tried paring the H7 to my iPhone app PolarBeat and the H7 was not recognized there either. So I was forced to assume the H7 was dead. That’s when I first contacted Polar about the problem. Days later they send mixed email messages so my confidence in their reliability and the quality of their customer service was diminished.
Back when I was carefully deciding which exercise monitoring device(s) to buy, I gave reliability a lot of weight, and I figured Polar to be well designed and reliable. Although the watch has proven good so far, the M400 fails to deliver what I purchased it for without input from the H7. I purchased the pair to work together so the watch would accurately display my heart rate and heart rate zone to me via. Also, at the gym it is the H7 that communicates heart rate data to the treadmill so the machine can accurately display heart rate zone and calculate other metrics like calories burned.
Here are some things about the Polar M400 that bug me a little:
• Syncing is slow.
My PC is very fast, yet it takes at least 2.5 minutes for the sync process to complete, even when there’s no new information from the watch or to the watch. The syncing software, Polar Sync, does not seem to have a programming design feature in which the watch software or the PolarFlow Sync software could detect that if the watch has no new data to offer and the Polar Flow web site has no new updates for the watch that syncing should end immediately and the sync operation should end immediately.
• The watch’s Sport Profile should optionally be displayed automatically.
I think it would be functional and convenient if among the watch settings I could optionally choose to have the watch automatically determine which display mode is appropriate to the activity I am currently involved in. How would the watch know? Here’s how: If the GPS senses motion at a steady pace that is within my walking pace range I am walking; conversely, if GPS senses that I’m traveling 55 miles per hour it can safely assume I am not exercising but traveling in a vehicle so it can shut down everything except the default display, If the sensed activity is brief—say less than 15 minutes, the watch should recognize that the current activity does not merit tracking, delete data collected, and return the watch to its default display, turning all tracking technology off. If I can come up with this, a designer can design it in and an engineer can build it!
• Charging of the watch is needed every two days on average
I feel as though this watch uses up too much power for the power supplied by the battery it contains. As an engineering suggestion, I would minimize the watch’s use of energy by having the watch do only what it has to do for the current display mode to function. The watch might shut down Bluetooth if BT is not being effectively used and shut down GPS monitoring if that is not needed. My point is that considering its relatively simple mission, the M400 has no business competing with my iPhone for charging time.
I'm also experiencing a problem with the cable that came with the M400, and I've had to use another cable from another device to sync the watch with my lap top. There is an issue I'm having with duplication of workouts on the flowsync website (https://flow.polar.com), I'm not entirely sure why that happens, maybe it's a setting, in my phone. I'll have to do some troubleshooting to figure that one out. Other than those issues, the watch does what it needs to do.
Good: This watch is super easy to use, mostly due to its lack of multiple functions. It gains a GPS signal fairly quickly, is waterproof, and is simple to pair with the HR monitor. The Polar Flow app is easy to use and to synch with fitness trackers such as TrainingPeaks.
Bad: The watch is difficult to pair with phones and the Polar scale (which also is not so good). Once paired, the watch takes an extremely large time to synch, and often fails. The watch also dies after almost 2.5h of recording, which renders it useless for serious endurance training. The GPS is fairly inaccurate, especially with regard to altitude gain/loss.
