There are hundreds of portable blood pressure monitors. Many of which are wrist based devices not much bigger than this Omron device. And others which are basically just the size of an upper arm cuff, which is much more accurate than a wrist based device. I wouldn't say this is a huge win at all. For some reason it can't even store more than 100 measurements, which makes no sense for a fitness watch.
