Is the Logitech MK850 Performance Wireless Keyboard and Mouse Combo worth it?
Yes — if one set has to serve a PC, laptop and tablet.
The keyboard has a gentle curve, a cushioned palm rest and adjustable tilt; the mouse is a contoured right-handed shape with a fast-scrolling wheel and side buttons. Both switch between three devices over Bluetooth or the included USB receiver, with Mac and Windows support. They run on AA and AAA batteries for 18 to 36 months, with no recharging. It's pricier than the MK540, the curve is subtle, and there's no backlight.

How we reached this verdict
Digital Trends found the MK850 well built and attractive, with three-device pairing, an ergonomic design and several angle settings, but a little pricey, with an understated curve and no recharging. That's the main expert test we found, so the verdict also rests on Logitech's spec page.
We compared independent expert reviews with the manufacturer's specifications, then checked it's sold at a major retailer where you live. We don't test products ourselves.
