Powr Labs Bluetooth Heart Rate Monitor Chest Strap, Heart Rate Monitor with Chest Strap | ANT+ Heart Rate Monitor, HRV Monitor Heart Monitor HRM Works with Strava Garmin Wahoo Polar Peloton iFit Apps

Not entirely OTF friendly. I needed to replace my existing HRM chest strap that i use for OTF; was keeping the pod, just needed a new strap as the connector points on my old strap were pulling apart from the strap material. After using the new strap for a week, I’ve had to finagle with it 4 of the 6 classes because it won’t ‘turn’ on, and its not the pod battery because that’s new. Sometimes, I’ve had to unsnap/resnap the pod onto the strap for it to pick up the reading, and i noticed in the last 2 classes, that once connected, the hr reading is jumping all over the place (ie, 77 bpm to 110 then 79 then 95, etc.) I was running at a steady pace on treadmill, so nothing that would have caused the spiking.

Great Communication. I had connectivity problems after about 3 weeks and the seller was extremely communicative, helpful, and friendly. Make sure to use saline solution, a little water, or tiny bit of saliva to wet the monitor on your chest to help connection

Great value. I have compared this simultaneously with an optical armband and Garmin watch, and the PowerLabs is quicker to repond to changes in heart rate during exercise and can read higher peaks during brief, hard efforts. For instance, if I go from resting to very vigorous exercise like pullpus, and back to resting- the chest strap reading raises faster and will peak higher, then start coming down faster than the optical sensors. And the optical sensors never register the true peak, because my heart rate is already falling again before they’ve caught up with it. However, on steady efforts like jogging or resting, they all tend to agree pretty closely with each other.I was concerned that the chest strap felt uncomfortable the first time I put it on, but I very quickly got used to it and now I don’t mind it at all. I run the contact area under water and/or dampen my chest where it sits to ensure a good contact and have had no problems with a reading. I’ve also run in the rain with it with no problems, so the monitor unit seems properly waterproof.It syncs right up to my watch and phone apps. The MapmyRun app was a little reluctant to connect, but it eventually did- perhaps because I gave up on it, connected another app, then went back to MapmyRun and it connected immediately.Another cool thing is my Garmin watch will automatically detect lactate threshold with this chest strap. which it cannot do with its own optical sensor or the optical arm band, and it detected my threshold within one beat of my result from the Joe Friel 30 minute test.Anyway- it’s working well so far at a fraction of the cost of a Garmin strap. I’ll update the review if anything changes.Have fun!

perfect garmin replacement. bought to replace transmitter for Garmin 830. Out of the box, the strap is basically identical to the Garmin strap. Paired with my 830 immediately, and worked 10.0 on a 90 minute ride. heart rate matched with watch. So far a solid value at half the price of OEM.

Works like a charm at a fraction of the price. I had been looking at both the Polar and Garmin heart rate monitors to replace my Garmin ANT+ monitor that does not work with my S22. When this popped up on sale I thought I’ll bite (especially after reading the reviews). It does not disappoint. The one thing I will say is make sure to pair the device via the app and not the phone BT pairing or else it will never pair in the app.
