I found the product to be simple to use and easy to carry around - the case kept it well protected in my cavernous purse! I am a heavy woman and have trouble with standard issue BP cuffs because of my arm size. This device was comfortable to use. I was monitoring twice daily for two weeks to get a handle on the effect of a new medication. We also compared the device readings to the Dr office readings - almost perfect match every time we tested. I have confidence in the readings and am far more likely to monitor because it is so simple and easy to use.
