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

Working well again after repaired / replaced by Polar. No complaints.
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.

Mostly good until failure after 5 months – But, 3 days later: spontaneous resurrection]
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.

Malfunctions almost every time
Does not work well at all. Frequently will show a bpm of ~40 bpms too low and then eventually (usually after a few minutes) rocket back to where it should be. This happens almost every time I use it and ruins my average bpm reading for the workout. I got this to replace a heart monitor that I got 5 years ago and had used frequently and figured it was due for a replacement. However, I’ve gone back to using my old monitor cause this one is crap. See the attached photo from about 2 miles to 2.5 miles for an example of the malfunction.

Very Good HRM – Quite Happy with It!
I got this for my Hydrow.It’s not subject to RF interference like my other HRMs. It stays charged for many sessions. The strap is good and easily adjustable.It’s easy to turn on and off and get on and take off.The charger is less than ideal since you have to remove then sensor from the strap, but it’s minor, and I’m being picky.It paired reliably and consistently with my rower and Matrix recumbent bike.It is not compatible with my older generation elliptical or arm bike, which use the original Polar standard.Ant+ and Bluetooth work perfectly.I highly recommend this HRM.

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。

El Polar OH1 es de esos dispositivos que, sin hacer mucho ruido, acaban ganándose un hueco fijo en tu bolsa de deporte. Es pequeño, ligero y muy fácil de usar, algo que se agradece cuando solo quieres ponértelo y entrenar sin complicaciones. Desde el primer momento transmite esa sensación de producto bien pensado, práctico y orientado a quien entrena de verdad, no solo a quien busca números bonitos.Cómodo hasta olvidarte de que lo llevasUno de los grandes puntos fuertes del Polar OH1 es la comodidad. Al colocarse en el brazo o el antebrazo, evita las molestias típicas de las bandas pectorales. No aprieta, no roza y no molesta, incluso en entrenamientos largos o con mucho sudor. Al final del entreno es fácil pensar: “ah, es verdad, llevaba el sensor puesto”. Y eso, en este tipo de accesorios, dice mucho.Precisión más que suficiente para el día a díaEn cuanto a la medición de la frecuencia cardíaca, el rendimiento es muy sólido. Para entrenamientos de carrera, ciclismo indoor, gimnasio o sesiones de funcional, los datos son estables y coherentes. No pretende competir con una banda de pecho en pruebas clínicas, pero para un uso deportivo real ofrece una fiabilidad más que correcta. Además, se conecta sin problemas a relojes Polar, otros relojes deportivos y aplicaciones compatibles.Ideal para entrenar sin relojUn detalle que marca la diferencia es su memoria interna. Puedes grabar el entrenamiento directamente en el Polar OH1 y luego sincronizarlo, algo perfecto para natación, deportes de equipo o sesiones en las que no quieres llevar el reloj encima. Es una función que no siempre se valora hasta que la necesitas, y ahí el OH1 suma muchos puntos.Autonomía sencilla y sin preocupacionesLa batería cumple bien: varias sesiones sin pasar por el cargador y una carga rápida que no desespera. No es un sensor que te obligue a estar pendiente del porcentaje cada dos por tres. Lo cargas, entrenas varios días y listo. Justo lo que se espera de un accesorio pensado para acompañarte, no para darte trabajo extra.Conclusión: discreto, práctico y muy equilibradoEl Polar OH1 no intenta reinventar nada, y quizá por eso funciona tan bien. Es cómodo, fiable y fácil de usar. Un sensor perfecto para quien quiere medir su frecuencia cardíaca sin ataduras, sin molestias y sin complicaciones. No es el más nuevo ni el más llamativo, pero sí uno de esos productos que cumplen exactamente lo que prometen… y eso, en deporte, vale oro.
