A review at this time is early as I have only worn the Qardio Core twice. I hope the Heart Function Clinic, of which I am a patient, Will use data from the Qardio core. I will also send Qardio Core data to a Heart Specialist wth whom I have an upcoming appiontment.

This thing is great and does what it is supposed to. I believe this could be the perfect one size fits all for health products, if they added a sleep tracker function and an exercise/workout function, being able to set what you want your heart rate at, and getting an alert if you aren't in the zone would be sweet. It would also be nice if the ECG would give alerts or make notes of irregular heartbeats. I think with enough public support, these could be added relatively easily, or at least allow select 3rd party apps for those functions. Either way, I own the core and the blood pressure monitor and love them both, probably get the scale someday.

The product would not attach and record properly to a person who is thin (without fat for padding) and feminine, frontal curves. Even placing the item upside down like the instructions said to, the product would work intermittently at it's best. The ECG recorded very wonky graphs. Set-up was very confusing and syncing the product with the cell phone app was very time consuming and inaccurate due to the poor instructions. Product was returned the next day.

I like the information that this provides me. It is comfortable to wear and easy to put on. However, it only gets four stars because it is difficult to take off and I have scratched myself on multiple occasions trying to do so. Otherwise, this is a great product.
