Query: Omron HEM-637 Wrist BP Monitor

A friend had purchased an earlier version of the Omrom BP monitor. I used it and wanted one like it. The monitor has a few more features than the older model. It appears to 'read' BP accurately. I tested it against an arm band electronic BP monitor and the readings were quite similar. The 'memory' and graphing features are helpful. I'd recommend it.
