When readers choose to buy Wirecutter's independently chosen editorial picks, it may earn affiliate commissions that support its work. Read the full article here .

Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too.

At Computex, the company made a little surprise by unveiling the VivoWatch BP, which is a follow-up to the original low-power VivoWatch from three years ago. We're looking at a handful of new features and improvements here, with the main highlight being the built-in blood pressure monitor -- a rare feature in the smartwatch category. The only other recent direct competitor is the Omron HeartGuide , which is also due to lau nch later this year. The VivoWatch BP won't be winning praises for its appearance. While the previously monochromatic high-reflective display has now gained some colors, it's also gained a much thicker bezel to accommodate extra sensors on the front. The screen is positioned i...
