Omron and A&D are made by the same company, and I have had two GPs and two cardiologists who like their BP testing products best. The arm cuff is considered much more accurate for most people than wrist or finger bands. I have an Omron that shows (and records) arrhythmias, and records several months' worth of data for two users and has a separate "guest" setting. It can also do things with the data, but I just use it to keep a list. It tests the cuff fit and positioning each time, and can do fancy BP tests like "average of three," where it takes three BPs quickly in a row and averages the results.
It doesn't make coffee, though, and there's no cupholder built in.
Best wishes,
