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 . After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms.

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

Sprint will give free data to Snapdragon PCs

ASUS may well have pulled out of the Android smartwatch market after its ZenWatch 3 , but it's actually not quite done yet with wearables. 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...
