Appears to measure BP but User Interface is hostile compared to an older Omron model.
Display contrast is bad plus there is not an internal backlight.
Indication of when device is at right height relative to heart is confusing and flakey, a blue light comes on and is usable briefly then goes out leaving the dim symbols, there is a flashing black symbol at bottom left. E for error is visible though. ;-)
Support is not good, staff have not tried their aldvice themselves..
I went out of my way and paid a premium price for Omron, very disappointed.
Recommend Against.
ADDITION: I was able to get my old HEM-637 working again by fiddling with the pump monkey motion inside it.
Far easier to use.
(The 'Gold' model with hostile UI does attempt to help you keep your arm at correct tilt, but that feature is not usable with the combination of bad display and awkward orientation.)
