Another Polar M4xx

June 2, 2017

Color: GreySize: Medium/LargeVerified Purchase

Pros: lots. It's an M400 that is lighter, has wrist based heart rate monitor, fast GPS acquire, and vibrating alerts.
Cons: the initial setup, poor customer support, and frequent sync errors. (More on this below.)

Delivery was extremely fast, but setting up the watch was a real pain. I tried it twice via phone (Android), failed both times at firmware update, having lost the Bluetooth signal (why does a product that's being sold for two days need a new firmware is another question). Finally I connected it to a computer where the setup, update and sync completed in a reasonable amount of time, and I only had to resync once because of some error.
The watch itself looks nice; similar to the M400 but different enough with its smoother touch and new wristband. If you had an M400 before, there won't be surprises, the menu is practically the same.

I'm yet to try it in action, when the pain of setup will have dwindled.

Update #1: now that I have used it in action, one more star. The M430 is just great, the fifth star is missing due to it taking three attempts to sync.

It is lighter than the M400, and while a couple of extra holes in the band don't seem to achieve much, it does help with the sweating.
The heart rate is more accurate than it was on the M200 (smooth raises and drops on the graph as I pedaled up slope and downhill, instead of noticing halfway that "hey, looks like we're doing something, let's crank it up from 90 to 155" ), even with indoor training where the wrist isn't in a predictable position like it is when running.
The buttons are quick to react, the menu is easy to use.
Finally, the silent (buzzing) alarm is here. Being an early raiser married to a late sleeper, a quiet way to wake up is cherished.

And now to the GPS.
Is it accurate? Probably is. It measures the same distance my other watches measured, give or take a few meters. But... It finds a GPS signal instantly. Right away. No waiting.

Remember when on cold, dark late autumn mornings you had to wait for a minute or two in the icy rain and wind for the GPS signal? Or when you wanted to measure the distance from the supermarket to your doorstep to prove it is *exactly* one mile*, and your husband and sister politely laughed at you while you waited for your watch to find that signal? Never again!

To summarize: set it up using a computer, be patient with the phone sync, enjoy the watch.

*It is.

Update#2: Attached is how a 6k run looks with the good old H7 sensor, vs the M430. There are differences, but they are minor, and the two graphs are practically the same.

Update#3: as expected, the HR accuracy is somewhat worse during weightlifting-type activities. (attached a second picture) Here I did some front- and back squats, followed by four minutes of deadlifts alternating with burpees (during which I placed the phone recording the H7 on a nearby shelf that was too far for this Bluetooth protocol, hence the gaps). The proportions are more or less there, but the numbers differ significantly. This is something I was expecting following my adventures with the M200; the accuracy improves with the band being tightened just the right way, and if one manages to sweat moderately, but (a) few are lucky enough to remain fresh and dry after 30 deadlifts and burpees (b) even then it is far from accurate.
If you want accuracy, go with the chest sensor.

I'll try biking next.

Update #4:
The watch stopped syncing. It connects, then claims that sync is completed after 1-2 seconds. I have to plug it into a computer. Disappointing.
After reinstalling the Polar Flow client, it syncs again, who knows for how long.

Update #5:
I think I figured out the sync issue. For whatever reason, the phone app switches the device off after every couple of syncs. Switching it on again (Settings - Devices) usually helps; if it doesn't, connect the watch to a computer or reinstall the app.

I'd like to mention how poor support from Polar was. I reported the sync issue to them, detailing all the troubleshooting steps I took; they responded after several days with a canned response suggesting some troubleshooting steps - some I wrote them to have tried already (wasn't even the full list), and nothing since.

The final verdict is 3 stars.

Great step forward, two steps back

July 30, 2017

Color: WhiteSize: Medium/LargeVerified Purchase

I had the M400 for two years before upgrading to the M430. I love that not much has changed. I think the heart rate is great and it seems to track reliably. The biggest regression is that Polar switched from a standard USB to a proprietary cable for charging. Why?!? Wireless syncing seems to be hit or miss. I was a nightmare to get going the first time. Then it seemed to sync great for a couple weeks. Now it doesn't sync wirelessly anymore.

I'm hopeful that the syncing can get sured up with updates, but the proprietary charging cable is a big disappointment.

Perfect running companion, very lightweight & feature rich.

December 21, 2017

Color: BlackSize: Medium/LargeVerified Purchase

After trying to use my Samsung Gear S2 smartwatch as a running watch I ultimately determined that it wasn't cut out for the task. I landed on the Polar M430 after comparing all the competition from Garmin, TomTom, etc. The Polar won me over because of its price and ease of use AND their software suite. Feature for feature this watch has everything most runners will need. It locks in to GPS SUPER fast which is great on cold dark mornings. The interface is easy and straightforward and provides a great deal of information on the oblong screen. It took me a while to figure out how to get the backlight to stay lit, and that's probably the one complaint that I have about the watch. Really take some time to read through the features offered vs. the competition and I think most people will find that the Polar is the best choice.

I was pleasantly surprised that it does cadence measurements without needing a foot pod! After doing research on why cadence is important, I was really hoping to find this feature without needing to buy a separate foot pod, and I think that the Polar was the only one that offered it on the watch without needing a foot pod.

Poor Build Quality

March 16, 2018

Color: GreySize: Medium/LargeVerified Purchase

I purchased this device in July 2017 and have worn it for 83 different run/bike sessions. It had all the features I needed (heart rate, water resistance, gps tracking); however, proved to be a poorly manufactured product. The buttons on the device became very mushy within the first two months. The two bottons in fact often get stuck in the down position.
The other buttons dont get stuck; however, the button action is very unsatisfying and gives very poor feedback.
I began the Polar warranty process online. Unfortunately, Polar does charge for shipping for repairs.
Great initial value with great features; however, I can’t recommend this product due to its poor build quality. You can see in the photo that I uploaded that the button on the bottom right is flush to the watch surface.

A. F. SLATER

Long Time Polar User

June 13, 2017

Color: WhiteSize: Medium/LargeVerified Purchase

June, 2017: I have been a Polar user for years (one FT60, three M400's, and the V800). I was really excited to get this watch, because I wanted to go strapless for my warmer long runs this summer. The wrist-based heart rate monitor was disappointing. It worked fine when I took it out for a short run (5k) and for a couple of indoor workouts, although the HR display went away for a few minutes. I decided to test it further in a half marathon I had last weekend; it lost my heart rate after mile 2. It picked it up sporadically during the race. I checked my Polar Flow stats and they indicated it only tracked my heart rate for six of the 13.1 miles. I had to pack it up for return after that. I will stick with my V800 for my long runs. Looking forward to my refund for the M430.

UPDATE, 12/2017: I recently purchased another M430 directly from Polar, in a size small. A review from Wearable indicated that they addressed the issue with the wrist based HRM (after Wearable pointed it out); apparently, it did not respond well to dark skin (which I have). The new watch I have is working much better than the first one I purchased, with indoor and outdoor activities; no gaps in heart rate. I purchased the small watch (only available in white) so it would fit closer to my wrist, just in case... I haven't completed a double-digit run with this one yet, but I am hopeful. Adding two stars based on their response to the Wearable review.
