Review on 🏋️ Shop the Magene Chest Strap Heart Rate Monitor: ANT+/Bluetooth 4.0 Compatible, Adjustable Strap for Peloton, Garmin, Wahoo & More - Works with iPhone & Android! by Sophie Martines

Should have listened to the reviews. Bought for cycling (indoors and outdoors) and the device doesn't stay paired with Bluetooth (iPhone) or ANT (on a USB extender). I tried them separately on the handlebars (less than 2 feet from the unit). I have used this device 6 times in one week and each time the device worked faster than the last time. Last time it was less than 15 minutes with a brand new battery. Needless to say, I am returning this item and going to my local bike shop and purchasing a Wahoo HRM.
