Great so far!!! It is taking me a while to understand all of the many watch options, but catching on fast. Enjoying the bread and butter components - heart rate pulse, oxygen level, sleep monitoring, and step monitor. Feeling better every day about the watch. 😁

CFDA Certification Health ECG Smartwatch With Blood Oxygen Heart Rate Monitor Sleep Monitoring Health Tracker Watch

Haven’t had any issues with this product at all. Very impressed.

This watch is amazing for the price. The heart health features are top notch. Having a pacemaker and being 85, this watch with the HRV, sleep, HR, and EKG features helps me monitor and improve my health.

The package arrived well protected and sealed, The truth is the watch is beautiful, it has no detail of imperfection and it is such that the description. The screen looks very sharp and the system goes smoothly as well as the connection to the application is stable. I have no complaints, so far all the tests I have done have been good and measure the health issue well. It's worth the watch and the store is very reliable.
