I have two omron BP cuffs and readers, they were ok but varied in their accuracy as I confirmed with doctor visits. This cuff, being two instruments all in once piece, is awesome. I have learned so much about my BP, heart rate, and ecg measurements that I am much more aware of my health and what impacts these measurements. Using AI interpretation of my ecg is helping me understand the various ways I feel at different times of the day. Having sleep apnea and using CPAP, this unit helps me understand when I have trouble breathing and how it affects my heart and pressure. Overall, so happy I bought this, now I hope it lasts and that the software and AI tools are always available. So far, no problems, oh, and the charging lasts long and is standard type C connector. So, there ya go!
