Scosche Rhythm R+2.0: Waterproof/Dustproof Armband with ANT+ & BLE Bluetooth Smart for Hyper Accurate Workout Heart Rate Monitoring with Wahoo, Peloton, LED Monitor, DDP Yoga, Strava

This works great for me (light skinned white male with a light tan) wearing it on my upper forearm while running. It never peaks or drops when it shouldn't and it picks up my heart rate change on intervals without delay (ramping up and download). Also had no issues connecting to either my Coros Pace 2 or Samsung Watch 4. I've compared against similar (same course and effort but at different times) runs with my Hammerhead chest strap and the graphs look the same (max, uphills, ..)The strap is great, it is a bit stretchy so I don't have to have it tight to be secure.For those that care where it's made, I went with the Scosche because it's not made in China (it is made in the Philippines).

I really love this product because it has solved the reliability issues I've been having with wrist-based watches. I was wearing two of them simultaneously (Garmina Forerunner 235 and Samsung Galaxy Fit2) during my runs, and I could observe the big differences; sometimes/days on, sometimes/days off probably due to movement or bad positioning due to tightness. The only agreement between them was when I was stationary. This product (btw, this review is for the second generation, Scosche Rhythm 2+ with the extended battery life), has been giving me readings consistent with my running, and the other products when stationary. I never liked chest straps, so this is just perfect for me being lightweight, practical, having excellent connectivity and battery life. The only issue I had was adjusting it to my upper arm; I just slide it up with the band closed, but it may feel a bit tight, and finer adjustment after you put it on is not possible. Still, once you've got a good fit, you're set. I haven't yet tested the stated 24h battery life, but overall I am very pleased with this purchase.

We bought this for use with our Peloton and it's been seamlessly producing data that's consistent with my HR monitoring watch. I like that I can quickly put it on my arm without wetting it down or wrapping it around my chest.If there's a mobile app for this, I must have missed it in the 4-stamp sized instructions!! But our use is primarily to connect it to the Peloton bike+, which it does easily.

Very happy with this.Comfort: Comfortable band that, you can wear on upper arm or forearm. More comfortable than other locations for HR monitoring like chest strap or wrist. Light weight.Accuracy: Works great on hairy arms. Seems more accurate than chest-strap based HR monitor.Connectivity: No issues connecting to Peloton bike, range seems better than Peloton chest strap. Haven't tried connecting to other devices.UPDATE: After 2 years of daily use, it died. Appears to be an issue with the battery not holding charge. It was good while it lasted. Removed 1-star because it died, but while it was working it was great.

The Scosche Rhythm R+2.0 is my workout partner on every front - yoga, treadmill, and outdoor runs. Its waterproof and dustproof design can handle anything. The heart rate monitoring is spot on, helping me push my limits. A reliable fitness companion for all activities!

Fool me twice, shame on me.... and that's what happened. I had a bad experience with the first-generation Sosche, and in fact gave mine away to a casual exercise friend. I guess I forgot that when, still eager to find an alternative to chest-strap monitors, I bought the 2.0.Surely they would address all the problems from the first gen when issuing 2.0, I thought!I was wrong.The Sosche monitor has performance issues which make it worthless: random dropouts and wildly inaccurate swings.I have tried it in several activities: rowing erg, standup paddling, road biking, indoor biking. In all of them, the Sosche:-- cuts out suddenly, with no environmental reasons for it to do so;-- suddenly starts reporting crazy high rates, and then overcorrects on a crazy downswing.I compared it with my Garmin chest strap and it's true, the Sosche results are way off. I wear it per instructions and have no skin issues that would create problems. The accuracy and performance are well below those of my Garmin Fenix watch (at least Garmin makes it clear to expect limits to the performance of their optical device).See the image showing Sosche readings: the program was 1 hour at steady 122-132 bpm, on a Concept II erg). No changes to position, environment, etc. Look how frequently the Sosche cuts out; and see how it runs way up above the actual heart rate, and then cuts out and/or swings low.Here is what the Sosche DOES do for my training:-- heart rates are higher, due to anger and frustration at the unit cutting off;-- times are slower, due to time spent fiddling with the device to get it to restart;-- data is useless for training records and analysis as the accuracy is terrible.The good? Nice design; fairly comfortable; good battery; simple ANT+ connections.More bad? A proprietary charger... come on manufacturers, use a "standard" USB-C please.Who is this good for? A chest-strap averse person with little more than a casual interest in the general vicinity of their heart rate.I cannot even give this one away in good faith. Just a waste.
