My previous blood pressure monitor was very inconvenient to use. It had to be plugged into an outlet and I needed an extension cord in order to reach one. By the time I got it set up, my blood pressure was much higher than it should have been. When I found this model on Amazon, I was happy to see that it charged by USB, and that it had a larger, easy to read display, and a pleasing voice gave me my results. The cuff was easy to put on and my arm didn’t feel like it was going to blow up while using it. I’m really happy that I found this easy to use product.
