OH1 + Waterproof Optical Heart Rate Monitor with Goggle Strap Clip and Armband – HR Monitor with Bluetooth, ANT+

UPDATE: I was ultimately able to get in touch with Polar. Mailed the monitor back to them and got it back fairly quickly. Not sure whether they repaired my defective one or replaced it. Have had no issues since the warranty honored - so upping my rating from one star. Definitely far prefer arm to a chest monitor. much more convenient. ##################### Over the years i have had nothing but frustration with chest strap heart rate monitors, primarily related to the difficulty replacing the battery. Also a hassle / inconvenient getting chest strap on. So after reading many reviews & getting recommendations from friends, i bought this monitor. For three months, i couldn’t have been happier! Easy to get on / off arm before and after workouts (primarily Zwift rides on my Wahoo KICKR). Fit well even if i was wearing tightfitting long sleeve shirt. Paired easily via Bluetooth with Zwift app. HR data seemed accurate. Knowing that i could track my HR hassle free with this monitor even increased my enthusiasm for my Zwift workouts... And it was great having a rechargeable battery (see below re: THE AGONY of replacing batteries in Polar chest monitors). Then couple weeks ago, the device suddenly stopped working. At first i thought i had not charged it enough between rides. But after charging again overnight, no difference - green light on indicating battery fully charged - but would not turn on. And then NO RESPONSE from Polar despite contacting their Support online and via email multiple times and providing serial # for hy OH1+. Hence I am giving up now and writing this 1 star review… I really thought i had finally found the perfect heart rate monitor after all these years but I guess now it is back to the drawing board… P.S. re: chest montiors - i previously had three Polar chest heart rate monitors that worked to varying degrees for varying times. All eventually became unusable because repeated attempts to try to open the back with a coin ground down the plastic so eventually had no way to open to replace the battery.… All still functioning - if i could get a new battery in - but useless once could not put in a replacement battery.

Great little heart monitor, I was able to pair it with my Garmin Instinct 3 watch (prone paddler, if you know you know). Works amazingly and is super easy to wear, charge, and clean.

Worked for 5 months [EDIT: 3 days later (today) it started working again. I noticed that it was flashing in the wall plug. Maybe it just needed a long rest after daily use for months?? ;) Fingers crossed that this will last - I had decided to just do without an HRM like our ancestors - changed rating from 3 to 4 stars] Cheaper than some alternatives , but after a full charge overnight, quit during a workout and will not restart. Compromises I was living with: did not work for swimming, not compatible with Chromebook, just Mac and PC. I was pleased with the accuracy and convenience vs a chest strap (matched data from Morpheus). I had a Whoop for a couple of years, but arm movement gave wildly inflated HR readings (e.g. swimming and sprinting). The choice of two apps , Polar Beat and Polar Flow, was confusing ,but the Beat app seemed to work better overall with my Pixel phone. The GPS tracking on an Android phone for walking, running, cycling measuring route, pace, HR are great. Also nice that the apps are free. Overall, longevity is the biggest issue and I dread wasting hours with Polar support again. They were responsive, but gave detailed and irrelevant advice. II haven't been able to find an armband HRM that has better reliability reviews.

Pretty basic but it is exactly what I wanted to use with my Garmin edge 530. Paired up and is recognized immediately. Stays paired and doesn’t power off like my Skosche did. I like the armband and it’s not very bulky. I think it’s a great meter at this price point and worth consideration. Charger could be lost easily but I am mindful of that so I hope I don’t lose it.

Long delay to refresh the HR variations. Good to run at constant pace only. Use five times only. The battery last few days without use. After 1 year without use, I try to power it on, after recharging, but it didnt turn on. Cheap fabrication quality. Way too expensive.

If you're serious about your workout data, you depend on the accuracy of your heart rate monitor. Unfortunately, most wrist based optical sensors are wildly inaccurate during activity. So that leaves you with two options: Chest strap, or arm based optical sensor. Chest strap being the gold standard for accuracy, but incredibly uncomfortable. That's where optical arm based sensors come in. They fall into a happy medium of "good enough". They are accurate, reliable, and more comfortable than a chest strap. If you've done your research, you know there are basically three options for arm based sensors - Wahoo, Scosche, and Polar. I won't get into all the details (See DC Rainmaker for a good comparison between the three), but I will tell you why Polar is the right choice. The polar OH1+ comes with a "goggle clip". Meaning, if you're a triathlete, you can clip the HR monitor to your goggles while you swim and it will record your temporal pulse for accurate HR data. That in itself is a nice feature, but what polar doesn't mention, and perhaps more importantly, is that you can use the clip anywhere there is reliable pulsation and a flat area of skin. Enter the "waist clip". I started to clip the monitor into my running shorts and cycling bibs and found that it will accurately record HR data from the femoral pulsation. Perhaps even better data than the arm (More stable, less light penetration, stronger pulsation etc). This means no arm band, no chest strap, just a small clip into my shorts which is secure and hidden. This takes comfort and accuracy to another level. For this reason alone, this is the only optical HR monitor to consider.

Serves it's purpose, cross checked with my Apple watch series 4, good consistency across the two. I find it useful to be able to track activities without my phone.

HIITを科学的に実行するために購入しましたが結果正解でした。

funziona perfettamente, mi sembra anche molto preciso, anche se non ho mai avuto delle fasce cardio tradizionali. Molto comoda da portare, personalmente la tengo sull'avambraccio sinistro

Vraiment génial et fiable

Très bien
