Review: Excellent Product. Accurate. - I purchased this as a replacement for another Bluetooth monitor I lost somewhere. I have AFib, and quick periodic monitoring of my heart rate is helpful. Cellphone apps where one holds a finger over the camera were simply not accurate. This one combines old-fashioned technology with an app that measures and then tracks the data in the iPhone health app.
Review: Functional and easy to use - ⭐️⭐️⭐️⭐️ The oximeter works well and gives quick readings for both oxygen and heart rate. The Bluetooth feature is a nice extra, although sometimes a bit slow to connect. Overall, it’s reliable and convenient for regular checks.
