Good replacement for Garmin HRM strap

I have used my Garmin Forerunner 910XT since it was first released in late 2011, and it came with a Garmin Heart Rate Monitor that mysteriously stopped working last month. It was time to buy a new one. I remember previously having used a Polar H10 Heart Rate Monitor that actually worked with the watch (because of ANT+ support), but I could not find it. My running buddy told me to try out the PowrLabs HRM that he got for Christmas and loves, and for half the price of a new Garmin HRM, I felt it was worth giving a try.PROS- Excellent price- ANT+ support allows it to work with my Garmin Forerunner 910XT watch and Polar treadmill at the gym- Bluetooth 4.0 support makes it usable with smartphones and mobile apps (and gym equipment that use Bluetooth)--- Tested with: Garmin Connect, Runkeeper, Nike Run, Runtastic, Zwift--- Works with Samsung Galaxy Watch with the Sporty Watch watchface (and should work with Galaxy Watch Active 2, too). Its HR data can then be exported to Strava and into Samsung Health and other services- IP67 water resistance: strap can be dropped into water for up to 3.2' (1m) deep for 30 mins. See TIPS section for more info- Strap is adjustable- No-question asked 1 yea

Works great with Samsung Health

This HBM works great. It snaps in place, and the chest strap is adjustable. It comes with a battery, so no worries there. The manual said the battery should last 6 months if used 2 hours per day. There is no obvious on/off button, so I guess unsnapping it from the strap turns it off? The only quirky thing is occasionally it says my heart rate drops significantly for a moment, and then pops back up. Not sure if its a device quirk, or something I need to discuss with my doctor. ;)I saw this device said it was compatible with ANT+, so I took a gamble it might work with my Samsung Note 10+. At first, I was disappointed because it didn't appear to work with Samsung Health, and the manual doesn't mention the app. But if you go into Samsung Health settings, click Accessories, and then click Scan, you can add the HBM (see photos 1-2). Then you get all this great additional information in the Samsung Health (see photos 3-7).Further reading suggests Samsung dropped ANT support on their newer phones, but some claim you can add an ANT USB dongle to the phone to make it compatible? I didn't try, so your milage may vary.Anyways, I'm glad I could get basic heartbeat data without having

Be sure to dampen the strap!

Update: After my 1-star unhappy review the company reached out to me and offered a refund AND shipped a brand new unit to try again. I have upgraded this to 4 stars. Even though he has a HR watch my husband needs this to display his heart rate on his phone mounted to his handlebars while he bikes, as he needs to keep it below a certain threshold.The initial try with the new one was disappointing at first. The battery on this unit was also weak so I replaced it. Dampened the strap as recommended and still nothing. Hmmmm...maybe it's me? The included directions are very vague, and the illustration of where to wear the strap conflicts with the website directions (also vague). I looked through a few video reviews and finally found an unboxing one that showed exactly WHERE to dampen the strap. Hint, it's not around the 2 circle spots behind the snaps for the unit, which seemed intuitive to me, it's the elongated, barely visible strips nearer to under the breast on each side of the unit. This time the app found it right away and I was paired and good to go! Did a test stationary bike ride and the HR was dead on with the bike, also matched up perfectly to the HR on my watch. After this i

Great addition to training.

I've used a Polar wrist watch style HR monitior for 20+ years. Unfortunately those units do not connect via Bluetooth (the older ones) so I was looking for a chest monitor that I could use with a variety of apps on my phone. There are several advantages to the phone apps like performance history, programed workouts, gamification (i.e. Peleton style workouts ia phone). This PowrLabs monitor fit the bill. Its a bit more comfortable than my Polar. No hard plastic agains the skin. The silicone grip surface is better than the Polar. The strap is easy to adjust and would fit a very large chest if required.I paired it with 3 apps on my phone. SWIFT, Cardiotrainer and the resident Samsung fitness app. My Note9 paired with the chest band easily and it kept in contact even as I walked into.another room after my spin bike ride.I like to monitor performance as I ride so I mounted a $2 phone holder to the bars and now I have high tech training.I look forward to traking my performance on some hikes and climbs.

Works great for a fraction of the price of a Garmin HR strap!

I've been using the Garmin HR-TRI soft strap for a while. But when the electrode started detaching from the band, and then the stitching where it fastens together started coming undone, I looked to get a replacement. Since that strap came bundled with my Forerunner 920XT, I was shocked to see the HR strap alone was over $100. I was a bit fearful reading the negative reviews, but took a chance on the PowrLabs product and I am very happy with the purchase. It easily and quickly linked up with both my Forerunner 935 and my Edge 520+. And to top it off, the company offers a year of free battery replacement. I'm hoping that my satisfaction with this is not short-lived. Crossing my fingers that I get years of trouble-free performance from this product. Happy to rate it 5-stars for now! Well done PowrLabs!

Highly accurate HRM

I purchased Powr Labs HRM because of inaccurate readings from my Apple Watch. Pairing the monitor to my Apple Watch via bluetooth took some work. The provided instructions refer you to a powrlabs website which then links Apple Watch users to a non powrlabs generic HRM site that provides troubleshooting tips. The chest strap placement video is useful. From my experience, get the strap tight to a point where the electrodes fully contact your skin, almost like a suction cup. Ensure the electrodes are very moist when contacting your skin. It took me six attempts. On the sixth attempt, and after two minutes, my Apple Watch discovered and paired the HRM.After pairing, you will still need to wake up the HRM before a workout. I opened bluetooth under settings on my Apple Watch, scrolled down to health data, touched the powrlabs tab and the watch linked to the HRM. When using the workouts icon on the Apple Watch, BPM from the HRM was displayed. BPM from the HRM are also displayed through the Heart Rate icon on the Apple Watch.PowrLabs solved the inaccuracy issue with my Apple Watch. The photo style sensor on the Apple Watch was reading quite high the frost ten minutes of my workout

Works great so far

This is the first chest strap I have used and so far it's great.I was tired of my Fitbit loosing HR half way through a workout. Constantly adjusting the watch strap, so I thought I would give this a try.I have used it for 5 weight sessions, a few runs, and a hike. No issues at all.Connected to Samsung Health perfectly (Have the chest strap on. Then the 3 dots, Settings, accessories, scan for accessories. I also had to use a few drops of water on the contact side)It will not give continuous HR(Again only tested on Samsung Health app). You have to start a workout for the HR to start tracking, but that's what I got this for.

Excellent device perfect to replace Garmin's.

It's been an excellent option, I bought it to replace a Garmin HRM dual and it was the best decision ever, I have worn it for running and cycling and can say honestly it is more precise and provides a better response than Garmin's.The reason for the change was that the Garmin HRM-Dual got broken on the battery cover without being damaged and they did not provide any spare parts to replace the battery cover, and PowrLabs battery cover design works without any screws (it won't get corroded), and the buttons that keep it attached to the strap are easy to clean.I also loved Packaging, simple yet functional.5 stars

Questions

Before you buy

Does it work with Peloton?

Yes. The Peloton Bike, Bike+, Tread and the Peloton app all connect to this monitor over Bluetooth. Open Settings on the Peloton touchscreen, choose Heart Rate Monitor, and select PowrLabs HRM. Our Peloton pairing guide walks through it step by step.

Will it connect to my Garmin, Wahoo or Apple Watch?

Garmin and Wahoo devices pair over ANT+ (or Bluetooth) in their sensor menus. iPhone apps such as Strava, Zwift and Polar Beat pair over Bluetooth. Apple Watch connects as a Bluetooth heart rate accessory in the Watch app on your phone.

How many devices can it connect to at once?

Up to three: for example your Garmin over ANT+, Zwift on a laptop over Bluetooth, and a phone app at the same time.

How long does the battery last, and what does it take?

A standard CR2032 coin cell gives 300+ hours, about 6 months if you train four times a week. For the first 12 months we replace batteries free; just email support@powr-labs.com. After that any CR2032 from a drugstore works.

Is it waterproof?

It is rated IPX67: sweat-proof and protected against submersion to about 5 feet. Rinse the strap after salty sessions and it will last. It is not designed for swim training (Bluetooth and ANT+ do not transmit underwater).

What chest sizes does it fit?

The included strap adjusts from 24 to 40 inches (71 to 99 cm) and stretches to about 61 inches at full extension. Replacement straps are available.

What is the warranty?

12 months, no questions asked. If it stops working, we repair or replace it. Returns are accepted within 30 days of delivery.

Why is the reading jumping around at the start?

Wet the two electrode pads on the inside of the strap before you put it on. Dry skin in the first few minutes is the number one cause of erratic readings on any chest strap.

How is this different from a watch's wrist sensor?

A chest strap reads the heart's electrical signal rather than estimating from blood flow, so it responds instantly to intervals and is not thrown off by wrist movement, tattoos or cold hands.
