Customers say

Customers find the heart rate monitor works well with Suunto devices and is better than older ANT+ units, with a perfect fit and snug comfort. The product is easy to pair and set up, and customers appreciate its quality, with one noting it's more accurate than wrist-based monitors. However, connectivity and reliability receive mixed feedback - while some report great connections, others experience disconnections, and while some find it reliable, others describe it as fragile.

Fail to do its job
The fit is more comfortable than the old ANT belt, and the belt stays stable throughout a long run. But unfortunately the reading is vastly sporadic and inaccurate, even when I wet the sensory area of the belt as instructed. Sometimes I would get a good and steady reading of 120s at the beginning of an easy run, and then suddenly it jumps to 210 for a few minutes, then drops dramatically to below 100, before returning to around 120s; other time I would get poor signal with a flat reading, then ok signal in the middle of the run, then poor again (like attached). I can hardly trust the HR data collected by this device.

    5.0 out of 5 stars Better Than Garmin
    Reviewed in the United States on July 17, 2021
    Verified Purchase
    I’ve been using this strap extensively with Suunto 9 Baro. First, the heart rate strap dramatically lengthens Suunto watch battery life, as Suunto automatically shuts off the watch HR sensor during exercise.
    Second, the HRM is far more accurate and reliable than the wrist HRM.
    Third, I have found the heart rate readings to be extremely accurate and reliable. As a 66 year old guy who likes very hard workouts, the HRM is my ‘bible’ keeping me in the right HR band during my activities.
    Finally, my Garmin HR monitor strap has been unreliable from day 1. Not the Suunto.

    4.0 out of 5 stars the suunto app, moves count, sucks
    Reviewed in the United States on December 13, 2017
    Verified Purchase
    1/23/2020 update
    the battery lasts a long time on this unit. I put my device down for a year. I put it on a few days ago and the battery had 40% capacity. I thought was pretty good. I wasn't able to pair my smart-sensor with the new Suunto App, but my iphone health app recognizes the device and accepts its data.

    The app does drop the sensor at night, when I am sleeping. So, I decided to buy the Suunto 3 fitness, that has the HR built into the watch and does 24/7 tracking. The watch gives me interpreted data on my sleeping and provides more value than I was trying to get from using the smart-sensor while I slept.

    I bought the smart-sensor for $55-ish in 2016. I think I got a great deal and a great product. But, I am enjoying the Suunto 3 fitness more.

    -----------------
    I really wanted this to work. I’ve had for over a year and it just doesn’t.

    It decides when it wants to work. I’m really disappointed. Such a waste of money.

    update---
    I got it to work with a third party app on my iphone

    another update----
    i upgraded to four stars. the moves count app is total crap on my iphone. but, using it with another app, it works perfectly every time. the battery life is pretty good to. i stored it for six months and the battery icon in the app and in the bluetooth settings indicated it was at 100%.

    5.0 out of 5 stars Love it!!
    Reviewed in the United States on August 12, 2015
    Verified Purchase
    Love it so far!!! Very small compared to other similar chest straps. I have previously purchased a Mio Fuse to get rid of the chest strap as they are mostly an annoyance, however I this strap doesn't seem to bother me. The actual sensor is about the same size diameter as a quarter and maybe thickness of 2-3 quarters strapped on top of each other. I'll still probably go back and forth between this and the Mio Fuse, but this is a chest strap I definitely dont mind wearing. Also of note it pairs perfectly with Runtastic on my iPhone 6 plus, and connects flawlessly to my Suunto Ambit3 as it should.

    This one new replacement after weeks and weeks of almost daily use mainly on 90’ Hot Yoga( can’t sweat more) stink too much of some sort of plastic/petroleum, even if I wash it after every session very well. I tried everything not even vinagre could get rid of bad smell. The old one original with the Watch never smelled bad after three years of heavy use !!

    1.0 out of 5 stars Sensor will not last longer than the battery - RUSTS
    Reviewed in the United States on July 23, 2019
    Verified Purchase
    This is the second sensor I've purchased in less than a year. When you first get it, it sets up perfectly well, all is great tracking heart rate and all at the gym, but magically it'll stop working. I usually get home from the gym and wash the strap right away and let it air dry and that was working fine, but ONE TIME I let it dry overnight with the sensor attached and now it's giving me trouble and refuses to connect. The watch says the sensor is paired, but when I start an exercise routine, it will not register the heart rate.

    I tried cleaning the sensors, thinking maybe it was causing the problem and changing the battery several times, even going out to get a fresh battery thinking maybe I had left mine for too long, and nothing. Upon closer inspection, there was a rust colored crust around the Right metal screw that snaps into the strap and when I looked at the old sensor it had the same issue on the same side.

    When I first had problems, I tried replacing the strap first, but then had to purchase the sensor and strap combo, so I now have 3 straps and have tried any combination of the sensors among the straps and nothing.

    I'm FRUSTRATED!! I can't get a years worth of use out of the SMART Sensor and shouldn't need to spend $60 every 8 months instead of $3 to change a battery. And if you go to the Suunto website, they have a software update that can only be completed when you pair the sensor through the Movescount app but it refuses to connect so essentially this is another dud.

    I'm going back to POLAR!!! I can't understand how someone that goes to the gym and occasional hiking can wear this thing down so quickly when real athletes are supposed to be using this on a regular basis without issues.

    This HR belt works great with my Suunto Ambit 3 and also Bluetooth’s with my phone when I’m using TrainerRoad. Works as described.

    5.0 out of 5 stars Recommended to pair with a watch, not the app.
    Reviewed in Canada on June 17, 2017
    Verified Purchase
    I wouldn't recommend buying this if you're looking to simply connect it to the Movescount mobile app. The app is notorious for not being able to maintain its connections.

    That out of the way, this belt is an excellent companion to any Suunto watch that is compatible with it. I have a Suunto Traverse and this belt was the only one that was compatible so I had little choice. I was a bit worried because of the previous reviews, not just here, but everywhere, with such a low rating. But happily, the belt works great with the Traverse. It's very accurate and hasn't lost connectivity yet. I use it about 10 hours/week and I have no complaints.
