I got this because I have a Renpho digital scale that's syncs with my phone and it has been wonderful. Unfortunately the first unit I received showed an error "EEA" and it wouldn't inflate. I chatted with support and they arranged for a replacement that arrived the next day. They also provided a prepaid return.The replacement unit works great, I can take multiple readings each day and can sync it to my phone.Only things I noted that are minor:It uses a different app than the scale to sync, I was hoping to use one app, but the scale isn't recognized by the blood pressure monitor app and vice versa. Not a biggie, was just hoping to use one app.The other issue is during the initial setup, the app asks you for your weight, height, etc. While you're putting this in the machine goes to sleep and it kicks you out of the app. Just keep toggling it between user 1 and user 2 every 30 seconds and you can enter it.Once that was done I've been very very happy with it.
