The Fitbit Charge 5 is our top recommendation for daily activity tracking. During our tests, it automatically and accurately detected a wide range of activities. Not all fitness trackers make good sleep trackers, but the Charge 5 managed to collect data from naps in addition to longer stretches of sleep. The Fitbit display is easy to read and the touchscreen is responsive and intuitive to use.

A hand vacuum can reach places that bigger vacuums can’t, and the compact shape makes it convenient for quick cleanups around the house. The Black+Decker is our pick for the best hand vac because it’s one of the strongest cleaners we’ve tested. Its unique, slim rotating nozzle helps it comfortably get into places that other hand vacuums can’t reach. We also appreciate the convenience of its built-in tools, like the flip-out dusting brush and the slide-out crevice tool.
