My wife has had the BP47 model for a year+ and it has been right on with what the clinic readings are. It's a great device.

The cuff has worn out though and the PRODUCT PICTURE shows the size as 13-17 in but the description says 8.7-16.5 in. I need the smaller size for my wife, which is what came with our monitor. We are trying to replace the cuff for our BP47 but don't want the bigger size. Please clarify what will actually arrive if ordered.

Seems to be a higher quality cuff than the original that came with the unit!
