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.

If you only need Bluetooth connection to a single device, this "older model" Polar fills the bill. It easily connects to my Garmin 520 bike computer and gives me continuous hr readings throughout my rides. I also wear it playing soccer and download the info to the Polar Beat app after the game. It records average hr, max hr, and distance travelled. It is WAY MORE COMFORTABLE than a chest strap and studies show it is comparable in accuracy.

I typically use the Polar chest strap for my workouts and cardiac monitoring. The chest strap has bluetooth, Ant+ and a 5Khz transmission. This works with just about any equipment and app on your phone. The Precor workout display on the AMT and other ellipticals requires a 5Khz transmitter. Most of the Polar chest straps have this built into the system. The optical transmitters do NOT have 5Khz. I checked every optical transmitter and they only have Ant+ and bluetooth. I was still interested in the optical device as I was having multiple dropped beats for up to 1-2 minutes with the chest strap. This was despite washing the straps, replacing the batteries, the straps and the device. This may be chest an inherent problem with the analogue system. However, it changes the "time in zone" and heart rate average if there is no heart rate being recorded. This device has good pickup, is light weight, and I can use it on my forearm, on my temple clipped to my sweatband, or almost anywhere. The cons are: 1.) It charges off of a USB separate clip device.... don't misplace it. 2.) It requires use of a bluetooth receiver. The App is ok. I'm not a fan of having to give my health conditions to Polar in order to use the device. It is part of the EULA... all the information is sent to Polar. 3.) I find a battery that is good for a year is easier than recharging this optical device. Essentially, the App is intrusive and more than necessary. The charger is proprietary and the device doesn't have 5Khz, but it does have a great pickup, no dropped beats.

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.

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.

I bought the arm (bicep) based heart rate monitor to track my indoor bike trainer sessions. For this it has been really good. I've had 2 minor issues that are inconvenient and expose Polar's absolutely horrible data practices. The two instances are a lack of the OH1 turning on. I go to charge it and after charging the device won't turn on. This happened when I first got it, within the first week, and 6 months later (just the other day). The only way to reset the device is to plug it into a PC and use the Polar Flowsync software. In order to reset the device you have to create a Polar account. It is here that the issues show up. Polar REQUIRES you to agree to a 7 item list (Privacy, Data, Terms of Use, Personal Data, Transferring Personal Data, Sensitive Data, Marketing) that tracks, analyses, and shares your data with whomever they want. You cannot reset your device without agreeing to ALL these things. Actually, you can't sign into your Polar account with agreeing to ALL of these things. If you don't agree you can't log in. They do allow you to agree, do your reset, and then disagree in your profile. But you get signed out. I can use it in this way without syncing the data to their data center and not being logged into their system. It is annoying and they have no right to my heart rate data and the associated personal data that makes heart rate data useful. I bought the thing, it is mine, but they require conditions to use their device. They can pay me if they want that level of data. But they won't. I'm working on finding something else. If you agree to a company having your personal health data for free without restrictions, Polar OH1 might be right for you. If you don't, I think you should look elsewhere. Here is a snippet of the items I don't agree with. Personal data* -I agree that Polar may collect and process my personal data as described in the Polar Privacy Notice. I can change my settings about this consent at any time. Transferring personal data* -I agree that my personal data may be transferred and processed outside my country of origin as described in the Polar Privacy Notice. I can change my settings about this consent at any time. Sensitive data* -I agree that Polar may collect and process my sensitive personal data related to my health. I can change my settings about this consent at any time. The sensitive personal data can be categorized under the data types listed below.

Replaced one that no longer held a charge

I tried this for a couple weeks, and IMHO it's only marginally better than a sports watch. My experience with sports watches are that they're ok at rest, but they become wildly inaccurate during exercise. The Polar OH1, for me, was fine at rest, but there was a significant adjustment delay when you're increasing your heart rate. This was checked by a separate device. As someone who has had heart issues in the past, this just wouldnt work. Battery life wasn't as advertised either. I got maybe 3 hrs max before having to recharge. I didnt let it go below 20% as I didnt want it to shut off mid session. I went ahead and got a refund for this and put it toward an H10. I've had an H10 in the past and was foolish to get rid of it. For me, they're a little uncomfortable, but I know the data is accurate. Plus the batteries are cheap if you don't buy them at WM or your corner DG or WG.

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.

Vraiment génial et fiable

Très bien

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 llevas Uno 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 día En 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 reloj Un 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 preocupaciones La 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 equilibrado El 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.
