Title: Cuff needs to be larger
Review: I think the unit is a quality piece of gear and the software is pretty cool but the unit reads at least 10mmHg too high compared to side by side doctor readings. The unit claims to come with a cuff big enough for very large arms and my 14" arms are well within the range they list but my doctor always uses a large cuff on me. I emailed the company to see if they had a larger cuff, they do not. They don't accept returns unless the product is defective. It reads fine on my apartment-mate.
