Awesome HRM...make sure device is paired properly

I had many of the same issues others had who posted negative reviews. The old HRM I replaced only had ANT+ pairing so it worked 99 percent of the time. Things got more complicated when I started using Zwift and had to use a Cable link device that converted the ANT+ signal to Bluetooth. When I switched to the updated HRM, I started having issues with it...hr would either not register or would stay constant. Then I realized I didn’t need the Cable converter anymore. Just make sure the Bluetooth connection is paired between phone or laptop to the HRM. Works every time now!

I’ve never had issues with Garmin straps. I not only have had several models, including the pre-2020 version of this same strap (more on that in a bit), but countless straps from Kickr, Polar, CooSpo, etc. I wish they would last more than a year or two, but some combination of sweat and dust always kills them (or bad design… the Wahoo straps always break at the snaps). As a strap, it is fantastic. I came back to Garmin because it was the most comfortable. Never had an issue pairing them with different GPS watches and cycling computers. Very comfortable, etc. It is also the worst, most environmentally unfriendly design and Garmin should be ashamed. I am not talking about the waste of Lithium Ion batteries. No. Before 2020 (it’s on their site), the strap featured the tiniest Phillips screws. Very easy to lose. Instead of fixing this issue, after 2020 they went to the smallest Torx size. Torx is good for some things. However the tiny Torx (it is the smallest size you can find a wrench for) just wants to strip. The first time I went to replace the battery, half of the screws stripped immediately. The next time I had to replace the battery, I had to jam the wrench into the head and apply lots of force to grip what was left of the Torx splines. Then one of the screws fell onto the floor of the workshop, never to be found again. So now, I am using electrical tape to keep the cover on. I wish I had kept one of my older straps, with the Phillips screws. Sure they were small, but they didn’t strip immediately. Basically, the screw choice is so bad that it’s almost like the strap is designed to be tossed when the battery dies. Shame on Garmin. Shame on the engineers and product team that thought that decision made sense. I wish I kept my old Garmin straps so I could mail them all to them. Maybe toss in all my other broken straps. Congratulations, you have created more useless garbage that will clutter landfills. M

Not Durable

3 years ago

Got this from REI 6 months ago. It was my 2nd purchase of the Garmin HRM. I was hard my 1st one. The strap accidently got into the dryer a time or two. So this time I was super careful. I used it 4 to 6x a week so I am a heavy user but for $75 I expect it to last more than 6 months. I followed manufacturer directions 100%.

Great start, poor conclusion

2 years ago

In the first couple of months, it was pretty flawless. Paired well with my Garmin Vivoactive in both running and cycling modes. I've been training Zone 2, so accuracy and responsiveness is particularly important for me, as HR is really the only that I pay most attention to. But in this new season, the numbers have been getting progressively less consistent -- to the point where it's all over the map. I tried everything with regard to washing and even giving the metal device contacts an alcohol cleaning after every run/ride. It helped at first, but then the numbers started their weird dance again. It's untrustworthy at this point. It's been 8 months, so that gibes with most people noting failure after the half-year mark. I will say that REI was cool about the return policy and I applied it towards the Polar H10.

Garmin Customer Service is Mega

3 years ago

Like a few others mentioned her, I had one that failed after a few months of moderate use. However, I contacted Garmin on a Saturday night in US and on Sunday received an email from them telling me they’re sending a replacement under warranty within a week. Prior to this, the HRM worked amazingly well. However, if you’re using it a lot, I’d recommend their Pro HRM which is more water and sweat resistant.

Very disappointed.

Product is slow to start giving heart rate data despite wetting my skin and the electrodes. And after only 4 months it is working intermittently, cutting out half way through my workout. I have other Garmin products and this is not what I think represents their quality.

Trash, works for a couple months and then stops.

4 years ago

I bought one of these, used it for a few months until it stopped working, argued with customer service for a couple weeks about why it didn't work, finally got sent another, and then it stopped working a few months later. Battery changes do nothing, they don't even last long enough to use an entire battery.

Specialized tool needed to change the battery.

1 year ago

This heart rate monitor came bundled with a Garmin Edge bicycle computer. It has worked well for 3 years. The battery wore down, as expected. Unfortunately the screws needed to remove the back panel require a #5 Torx screwdriver. I didn't own one, and only found out that I needed what I view as a specialized tool by searching on the web. I don't recall the documentation warning me that a Phillips head would fail. The battery is the same as that used for Apple Air-Tags, so I had one on hand, but I had to buy the Torx screwdriver. The monitor is working fine now, with the new battery.

worst HR monitor

5 years ago

I purchased this to pair with my Garmin Fenix 5 plus after the Garmin customer service suggested it. After some initial trouble pairing it, it never read above 79BPM. Thought it might be the battery, so I replaced the battery. Same issue again. Disconnected and tried to reconnect to no avail. Replaced the battery again and still nothing happened. Then thought it might be the watch do I tried pairing a Polar HR monitor. The Polar paired instantly and read accurately. I will be returning this unit.

Only lasts about 6 months...

9 months ago

I am a recreational user...typically around 30 to 50 hours per month of use while cycling. When it works it works great. But, despite rinsing them off after every use, I can only seem to get 6 months of use out of these straps before it kicks the bucket. On the positive side, I'm saving a lot of money on batteries as they don't last long enough to change them. I am deeply invested in the Garmin ecosystem but, I think I'm going to go with a polar strap next.
