5.0 out of 5 stars Perfect app; strap needs DIY modifications; works great with my old polar watch
(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } The strap sucks. If you have no lats, maybe it won't slide down your body as you run. But for those of us with big lats, you have to modify this thing. You can either modify the strap, or buy the $40 Polar Pro chest strap (you’ll have to replace any strap you get probably every 6-12 months so keep that in mind). I haven't tried the outrageously-priced Polar Pro but it's the only one on the market that has grips all the way around the strap, not just in the front.The chest strap can be easily modified as follows:Buy one of the "zig zag silicone grip wave bands" you can find online, and sew it (or use fabric glue or something) to the inside of your Polar chest strap and it actually stays in place while running! Just make sure you get the strap customized to your underchest first, and give yourself some space for the inevitable long-term loosening of the strap (you might need to tighten it gradually over time).Without the extra grip, you have to find the perfect balance through much trial and error between too tight and too loose. Too tight, and it creates a little cavity where the electrodes are between the strap and your chest (so it gives you terrible readings, if any). Too loose, and it falls down to your waist.I also found that using a small dab of electrode gel on each of the two electrodes on the back side of the chest strap (enough to cover just the two circles on the strap where the strap touches your chest) makes a huge difference in getting a consistent, accurate, read. Don't use water, it just doesn't work nearly as well.I love the Polar Beat app it comes with! It was the best free app I could find for Android for a heart rate monitor. I'm sure there are probably better paid ones out there but I didn't try any of them so can't attest. The Polar Beat app gives you a graph at the end of your workout that shows your heart rate over time, and tells you how many minutes and seconds you spent in each of the 5 heart rate zones (50%-60% of max heart rate = zone 1; 90-100% = zone 5). It has certain modes that track your GPS location for accurate maps of your runs/rides and the app will tell you every mile when running how long your mile took, your pace, and average heart rate. I've never used it for a bike ride.It also tracks calories very well and whenever it doesn't get an accurate read, it does a pretty good job "guessing" (better than the old Polar Watch I have). If I start my workout on the Polar app first, THEN start the workout on my Polar watch, it will let me use both to track my workouts which is great. That way I can leave my phone in my gym bag while running around the track, and use the watch instead to track % of max heart rate. It's also nice when using my phone for anything else while I'm doing a HIIT circuit or on the exercise bike, that way I can just look at my watch to see my stats. I don't have a smart watch so can't comment on how it works with that. I think you might need to get the latest and greatest to pair it to two or more smart devices at once. But this one works perfectly for one smart device and one dumb device.
5.0 out of 5 stars Works great.
Pairs with my PRECOR treadmill. But treadmill display is not as accurate as my iPhone. So I just use my iPhone while working out. I like the app.
1.0 out of 5 stars No one should buy Polar items.
This is pure e-waste. Don't bother with it whatever your usecase. it never stays connected to the app, it always drops. it doesnt help me monitor my heartrate because i have to do specialized programs in the app to see anything. truly I don't understand why a factory would make these then let customers use them with the utter travesty of an app that is Polar Flow. 0/10 stars, I'm very frustrated!
5.0 out of 5 stars Easy to use an efficient.
I love the Polar H9 heart rate monitor. It's easy to use and works flawlessly. This is my second purchase and the first one lasted about 5 years.
4.0 out of 5 stars Terrific in All But One Respect
After using an earlier generation Polar sensor for many years, I decided to buy this one when I bought a Garmin Venu 2 smart watch recently. The earlier Polar model couldn't be paired with the Venu 2.This H9 model paired with Venu 2 very readily, and it's communicating my heart rate to it as reliably as one would expect.My one and only complaint is with the elastic band's clasping design. It's extremely simple, and it's in that simplicity that I think Polar missed the boat. There's a thin plastic hook that one inserts into a small fabric "eye." Not only is the fabric's opening so small that it can be hard to see, but it has a tendency to come unhooked occasionally. The design could be much improved with an equally simple snap. Otherwise, the band is comfortable; and the transmitter functions great.Update after 2 months: After using the H9 6 times a week, it needs a battery (CR2025) after only 2 months . Perhaps the original battery was of low quality. I would have expected longer battery life. Fortunately, it's designed so that the battery is easy to change.
5.0 out of 5 stars Better than Garmin HRM Dual
I've only owned this for about 2 months now, with about 3 - 4 hours of intense sweat contact per week. But my impressions so far it's better than Garmin HRM Dual that lasted around 1.5 year with similar use pattern. The Garmin had noticeable corrosion on metal contacts, the metal buttons on strap was separating, would drop connections frequently towards end of life, and the ultimate failure points around screws on plastic unit seemed to be a silly design flaw. Unless the Garmin was a case of planned obsolescence, in which case kudos to that Garmin engineering team, it was an inferior product compared to the Polar. The Garmin failed because the thin plastic pieces beneath the tiny screw heads cracked and crumbled away so back cover could not hold battery in place. Seal was broken and the internals corroded to failure. All those weak points on the Garmin seem to be addressed on the Polar. In addition, the Polar actually pairs better with my Garmin products more quickly, consistently, and easily without having to wet the strap when I first put it on. Polar strap is a little narrower but for me its more comfortable because of softer elastic fabric. Minor downsides, the Polar strap loop and hook is not as robust and easy to use and narrower strap sometimes gets a little bunched up.

BUENA BANDA PULSÓMETRA
Compré el Polar H9 durante el Black Friday con una excelente oferta, y debo decir que estoy muy satisfecho con mi compra. Este sensor de frecuencia cardíaca cumple su función de manera eficiente y confiable. No he tenido ningún problema al sincronizarlo con mi reloj Polar M430 ni al usarlo en pruebas exigentes que lleven mi corazón al límite.Durante mis entrenamientos más intensos, el Polar H9 ha demostrado ser preciso y consistente. No ha habido ningún salto o error al monitorizar mis pulsaciones, lo cual es crucial para un seguimiento preciso del rendimiento. Además, es muy cómodo de llevar y no molesta al correr, siempre y cuando lo ajustes correctamente, como cualquier otro pulsómetro.En comparación con las mediciones de frecuencia cardíaca en la muñeca de mi reloj, el Polar H9 ofrece lecturas mucho más precisas. Para aquellos que buscan un seguimiento más avanzado, es posible que necesiten invertir en opciones más tecnológicas y costosas. Pero para mí, el Polar H9 cumple con creces mis expectativas y necesidades.
