MicrosoftKeyboard/Mouse PY9-00002 Desktop 850 Combo Wireless Black with AES Retail

Works perfectly. I needed to replace my old Microsoft Keyboard and Mouse. This did the trick with no drama.

it works

Everything is great except the space bar which sticks terribly.

Using a HDMI cord, my small computer screen exploded on my TV, enabling me to see clearly and do spreadsheets and play midi notation with out squinting. The music sound was also using the TV speakers instead of the computer speaker. Yes, using a boom speaker I can transfer the sound , but speakers on the TV were automatically turned on. It was fun.

This works great, exactly what I wanted.

Very good and durable product. Product is compact and keys are easy. Small for large hands.

I had the 800 combo for years and loved it. I expected to love the 850 combo. It was horrible!The keyboard is nice and designed the same as the 800 combo. The problem in the mouse wheel. The wheel sticks and as you roll it jumps up and then you try scroll slowly and it still jumps. Must be something wrong with the guide underneath. I finally bought a cheap logitech combo that I had bought for my work computer. The mouse is wonderful and the keyboard does not take up as much space. Shame on Microsoft for replacing the 800 with this product. Buyer be ware!

I needed to replace my 6 year old keyboard. This was the same thing so I felt comfortable with it.
