I've been using chest straps for the last 15 years. Never really any issues other than batteries dying. Gone through Garmins and then maybe 3 wahoo ones. All fine I guess, the Wahoo's only seem to last a couple of years for some reason. Now, pre-setting the strap for these has always been just one of those things I did, either under a tap and embrace the chill when you put it on, or the spit and rub which always had a mildly kinky vibe to it :) Not to mention the more often than not coffee scented strap after a while. Then I finally cave a get this little switcheroo. I wasn't sure how good it would be using the same kind of system that watch based heart rate sensors use (which always seem to lock on to cadence for me). But this thing is solid. Comfy, requires no spit and means i can add a new weird tan line to my arm come summer. But in seriousness, it's accurate, connects to my suunto watch, (i've not used the coros app), is accurate and i honestly forget I'm wearing it. Plus being that it sits on my upper arm and not at the core of my body, it doesn't get anywhere near as sweaty in the heat. Review: The best optical sensor, but swap the strap - The best optical sensor (I tried them all). Extremely accurate around the bicep and even the wrist (not usually advised due to inaccuracy). Easy to charge, usb-c, and the auto on/off works beautifully. The strap is too uncomfy and pinchy, but is easily swapped for a replacement Coospo Hw9 strap which is the best (feed it through in one loop and trim the bits). Like all opticals, readings lag a few seconds behind realtime, and it takes a few seconds to dial in after putting on. ## Features - COMFORTABLE AND QUICK CLEANING: The fabric band is soft and breathable, more comfortable to wear than a chest strap. You can quickly clean the band by removing the sensor of COROS heart rate monitor chest strap ."COROS heart rate monitor armband is designed for measuring heart rate during sports and activities.

The COROS HR Monitor can also pair with any fitness tracking watch, gym equipment, cycling computers, and more.** **Q: Does the COROS Heart Rate Monitor work over tattoos?** A: Depending on the density of the tattoo, the heart rate monitor may be able to get a reading but it's not guaranteed. If you have tattoos, we recommend adjusting the placement (bicep, forearm, opposite arm). **Q: How do I charge the COROS Heart Rate Monitor?** A: Connect the charging cable to the back of the heart rate monitor. An orange light will appear while the monitor is charging. The light will turn green once it's fully charged. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great but you don't get to spit on you hand and rub it like you do a chest strap...... :) *by B***G on 22 March 2025* Game changer.

Easy to set up, works great with my garmin forerunner. I forget that I’m wearing it so much more comfortable than a chest strap. Used 5 times so far so can’t comment on durability but so far so good ## Frequently Bought Together - COROS Heart Rate Monitor, Comfort, Easy to wear, Auto-wear Detection, Advanced Sensor, Precise Data, Bluetooth, 38 Hours Battery Life, Compatible with up to 3 Connections, for Run and Bike - COROS PACE 3 Sport Watch GPS, Lightweight and Comfort, 17 Days Battery Life, Dual-Frequency GPS, Heart Rate, Navigation, Sleep Track, Training Plan, Run, Bike, and Ski (Black Silicone) - COROS POD 2, Watch Sensor Accessory, Accurate Indoor and Treadmill Distance Measurement, More Sensitive Real-time Pace, Improves GPS Data, Clip onto Shoes or Waistband only Works with COROS Watches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/651312561-heart-rate-monitor-comfort-easy-to-wear-auto-wear-detection](https://www.desertcart.vu/products/651312561-heart-rate-monitor-comfort-easy-to-wear-auto-wear-detection) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-11*
