The device itself is easy to use. The software for it (as in the app you can install to sync your readings to your phone or tablet) could be better. If anyone other than you tries measuring their blood pressure there's no way to indicate this isn't you - and when you sync your readings you'll get anyone else's logged along with your own, which can really throw off the averages. You can delete individual readings, but it would be far nicer if there was some way to manage multiple users of the device. On the whole though, it's easy to use, seems to be accurate, and I can use it myself without assistance, and that's what I need most of the time.view more
