Reviewed in the United States 🇺🇸 on June 3, 2023

Size: M-XXLVerified Purchase

i was very unsure of this monitor due to pass experience with other chest straps. many years ago before the blue tooth i had a polar that paired with a watch which i liked, however the old style are ever hard to come by these days. i am more of a low tech guy. i have been working out majority of my life cardo, lifting, and yoga and with the same trainer for years. for unknown reason i developed very large blood clots in my lungs. that side lined me. it is a long slow climb back to where i was fitness wise. I returned to the gym earlier when most are only starting to walk again. there are no true studies this area on fitness rule of thumb from doctors is rest minimum active and no lifts. however i believe physical fitness is key to health so i returned gym to see what i could within guidance of my doctor and trainer. Doctor wanted an oximeter (checking my oxygen level every two minutes) my trainer also wanted the heart monitor. finding the chest strap monitor was a challenge. quick side note my return to the gym was humbling things of the past i viewed as child's play were now challenging. i tried other monitors they didn't work and wanted a monthly fee for their app that they pair with. The polar beat app is free easy download and easy to use with a long list of various fitness activities. i would like to see a cardo circuit added. the chest monitor paired relatively easy with my iphone and the app. this chest monitor also paired with every piece of cardio equipment in the gym automatically (treadmills, bikes, stair climber, stride elliptical, elliptical, rower) The important art is the monitor is accurate. i have tested its readings against the equipment of my oximeter. due to being a lifter i needed to find a strap that would comfortable on a guy with a large chest. This one does however i would like to see a couple more inches added to the strap the idea that only individuals who do cardio with a 36 chest wear these is kind of monitors is nuts. the main reason why lifters don't wear them is finding one that fits. my only issue is the battery when quickly. i suggest keeping an extra battery on hand in your gym bag. i do the same for the oximeter. In closing i do suggest the polar chest strap monitor.

Works as advertised

Reviewed in the United States 🇺🇸 on May 12, 2023

Size: M-XXLVerified Purchase

I have used this for a few weeks now and it seems to be working as advertised. It automatically connects to my treadmill and elliptical and tracks my heart rate accurately compared to taking my pulse. It does occasionally lose connectivity to the treadmill and it is not clear why. Grabbing the sensors built into the treadmill will override the connection and connectivity reestablishes after releasing the treadmill built-ins. I disconnect it from the belt when not using, which supposedly helps extend battery life but it would be nice if it had a proper on/off switch. It would also be nice if it used a CR2032 battery instead of a CR2025. The former is more readily available around me and not that much larger. I might try it with a CR2032 to see if it will fit.

I keep a small spray bottle filled with tap water on hand to help with connectivity. After I get the sensor situated on my chest, I turn it down and mist the electrode area and adjoining skin. This improves the initial heart rate detection.

It works. Is it accurate?

Reviewed in the United States 🇺🇸 on April 28, 2023

Size: M-XXLVerified Purchase

The new strap/transmitter synced immediately with my old Polar FT7 wrist monitor. (Which I hope lasts a while more, as newer Polar sport watches are loaded with features I don't want and are expensive.) Very quickly synced with the Polar "Beats" app as well. The app is very useful when doing cardio on elliptical and exercise bike, not so much when strength training. BUT using the watch and app simultaneously shows that they give different HR readings from the same transmitter - often differ by 10-12 bpm and at times by 20 bpm or more. I don't know which (if either) is accurate. One quirk is that it's necessary to start the app before getting on the cardio machine - otherwise I get a notice that it can't sync because "it" (presumably the transmitter) is already synced to another device (the cardio machine, I assume).

Good Sensor, Not So Good App

Reviewed in the United States 🇺🇸 on April 25, 2023

Size: M-XXLVerified Purchase

The media could not be loaded.

Pros:

Good sensor, comfortable, replaceable strap, good battery life, durable enough for my needs (running).

Cons:

Polar Beat app, which you need in order to use the sensor (without having to buy an expensive watch) has bad audible alerts.

The audible alerts are not always there, and they have weird jargon. So instead of saying "Zone 1" or "Zone 2", which is what is shown in their app, the audio says "You are burning fat".

Also, a Zone can have multiple audio alerts, so "Zone 2" can be "You are burning fat", "You are improving fitness", or nothing at all.

Also, the same audio alert can be shared by multiple zones, so if you hear "You are improving fitness", you can be in either Zone 2 or Zone 3. "You are burning fat" can be in either Zone 2, Zone 1, or Zone 0 (when you start the workout).

Not good for outdoor running where you DO NOT want to look at your phone to keep track of HR, so you can avoid getting hit by a bus, tripping over a log, or falling into a ditch.

Since the sensor cannot be used without the app (or other equipment that can display heart rate from the sensor), I think it is fair to rate the sensor with the app that the manufacturer intended to use with the sensor.

Hopefully the app gets better so that the sensor can get the rating it deserves.

Check if it's compatible with the other apps you're already using

Reviewed in the United States 🇺🇸 on April 5, 2023

Size: M-XXLVerified Purchase

The device by itself and the polar app it's great on its own however, when i tried to pair it with my samsung phone, that is when i had issues with it.
You'll have to research a few things here and there then jump through some hoops just to pair it with my samsung health app.
Even with google fit that it's supposed to work with, it didn't pair with it that easily.

Worked well for me. It doesn’t always connect well with Apple products especially the watch or update the daily rings. Would like to see better compatibility with these things as Hr wouldn’t show up on the watch at all.

Good hrm but expensive

Reviewed in Singapore 🇸🇬 on November 15, 2021

The sensor worked out of the box and easily paired with various app. The polar beats app allows you to measure your v02 max which is a nice touch.

However, it is 2 to 3 times the price of a xoss or magene hrm. Those however only provide heart rate
