When thinking about purchasing this product, I consider these three things first. 1. Is durable and quality construction important? 2. Is compatibility and easy of use with my smart devices important? 3. Is it beneficial to record my weight, fat %, and BMI on a daily basis to track my successful efforts over an extended period of time? I found all three of the above met in the QardioBase 2. It is well constructed, obvious from the weight and durable structure prevalent when removing it from the shipping box. Connection was very simple. It was connected and I was able to get my first reading within five minutes after opening the scale. The final thing to note is the convenience of viewing past measurement so my successes and challenges might be reviewed. Since I am on the Apple platform, it is important to note that it work very well with Apple Health and subscequently the App LoseIt to incorporate my daily weight. I would definitely recommend this product (and the QardioArm).
