While the price and features are great on paper, in practice something doesn't work right. 50% of measurements are aborted by an error message, and never reach full cuff inflation. That is exteremely annoying. Unit is sent back for refund, and as much as I wanted to stick with Omron, I have ordered a different vendor instead.
