Garmin  HRM-Dual Heart Rate Monitor and Chest Strap

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%.

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!

It gets disconnected from Garmin Fenix 6 which is very disappointing, tried it with strava didn’t get more accurate data than Fenix 6!

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.

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.

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.

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.

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.

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.

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.
