PROS / The keys are concaved and have good responsiveness.
CONS / The keyboard feels flimsy.
VERDICT / The wireless mouse and keyboard are basic in functionality, lacking any extra features, but this combo will suit you if basic is good enough.
The Microsoft Wireless Desktop 850 has a standard keyboard style with a basic layout. You won't find many additional features on this wireless keyboard and mouse combo outside of a few volume buttons in the upper-right corner of the keyboard. It's among the most basic and least expensive combos in our comparison.
Upon holding the keyboard for the first time, it doesn’t feel durable at all. There is a black plastic cover that sits on top of the white base, and it feels like the two could easily be separated. The keyboard is incredibly light, only weighting 1.2 pounds, but it doesn't feel solid. An accidental drop might damage the keyboard. That being said, it is lightweight and slim enough to be fairly portable. When you have your laptop, keyboard and mouse in a bag, every pound counts.
As far as comfort goes, our group of reviewers enjoyed typing on the Desktop 850. Most of our reviewers liked the responsiveness of the keys as well as the concaved shape of the keys to keep your fingers in the right spot to eliminate errors. This wireless keyboard doesn’t have a wrist rest, but our reviewers didn't seem to mind that.
The wireless mouse is basic and has an ambidextrous design. It doesn't have any additional buttons beyond a right and left click and a scroll wheel. In our comfort testing, the general consensus was that the mouse was one of the least comfortable in the group. The arch doesn't come up high enough for the palm to rest on it. The palm rest is also narrower than most, making it feel less comfortable than other mice.
During our surface testing, the mouse did great on wood, laminate and denim, but it struggled on glass, marble and carpeted surfaces. Carpet really gave the mouse problems. The mouse was ultra inconsistent as well and made the cursor jump around. On marble the mouse was also pretty unresponsive. It is best to stay away from those surfaces.
The wireless mouse and keyboard are powered by two AAA batteries in the keyboard and one AA in the mouse. Microsoft claims that the keyboard can last up to 15 months with regular use while the mouse can only last eight months. This isn't nearly as good as some of its competitors that claim to have battery life up to three years.
The Microsoft Wireless Desktop 850 is a basic wireless mouse and keyboard combo that is inexpensive but lacks many features its competitors offer. The keyboard doesn't feel durable, but our reviewers liked how it felt after extended use. The mouse is good for both right and left handers but isn't comfortable. If you want a basic wireless keyboard and mouse combo, this will do the trick.
