Review on 📈 Monitor for Performance by Brett Morrison

great product! The ECG lead is accurate, but only if you hold the device without moving. Any slight movement changes the reading, but so does a professional 12-lead ECG. You can store information - 100 reads - with no monthly maintenance or fees. You can also connect it to your mobile device via the app. This device accurately measures heart rate, heart rate, oxygen saturation, temperature. It also has a pedometer function, but I haven't used it yet. If the price makes you hesitant to buy this, it's worth every penny. In addition, multiple users - 3 plus a guest - can track their individual data. Great, great product.
