Microsoft Wireless Keyboard 850 Usb Receiver Lost

I was looking for a wireless keyboard and found this, having the usb work as a wireless receiver for the mouse and keyboard its super convenient.

I used to own a Kensington wireless mouse because I liked how it looked. But it had lousy wireless connectivity and it constantly dropped its signal for no apparent reason. Seeking to replace it, I came across the Microsoft mouse at my neighborhood consumer electronics retailer. I found this same mouse at B&H for $20 less. I love this mouse. It's got a stylish appearance, the wireless signal is rock solid...no more dropped connections and it tracks great. I also like how I can easily power it off to save battery life. The only drawback is that it requires its own USB antenna so when you're using Microsoft's equally stylish wireless keyboard, you're using up 2 USB ports: one for the mouse antenna and one for the keyboard antenna

I use the arc wireless mouse by microsoft. This product is great, the mouse fits well in the hand. The usb transciever is very small and has less risk of breaking or damage while in the computer. One disadvantage is that if you have a lot of programs running, then the mouse lags,,

I lost the receiver of my space mouse, and this was a great price. If I ever switch a 3D keyboard or mouse, I'm all set.

Went to use my Vello wireless remote and discovered the cable to connect the receiver to my Canon was lost. This is an exact replacement cable. I plan on securing it to the receiver unit with velcro or elastic.

I've tried almost every type of different wireless keyboard and mouse to use with my computer, which is situated behind speakers, 10 feet away from where I use them, and this has been the only receiver with a consistent connection. Its accurate enough to play games like call or duty, or to do photo editing. The keyboard is pretty nice, I like it but some people don't. The mouse is a little small, but makes up for it with a very nice mouse wheel and other frills. But if you're considering this product for a home theater PC, all that is more or less moot, because IMO the Logitech unity receiver is the only option. TL;DR: don't buy anything but a Unity receiver device, such as this one, for long distance computing usage.

This keyboard has a plug in usb and can be wireless unless charging. It connects better plugged in all the time.

The keyboard and mouse have worked flawlessly from the start. The single receiver for both devices is plugged into a USB port in the back of the desktop. The computer is in an enclosed compartment in a desk and there are no communication problems. Best of all, no wires.

Good feel when typing, Keys light up when in use or when keyboard senses your hands. Quiet, connects using USB receiver. I wish the keyboard would use the same USB receiver as my HP mouse, but you must use the keyboard receiver for it to work. You could connect via bluetooth but I have not tried that yet.

I bought mine from Bestbuy, albeit price-matching I had to pay extra for in-store tax purchase. Two factors I love about this keyboard:  Unifying Receiver and Illuminated keys. Since the new 2018 MacBook Pro build in keyboard, or even the Apple Keyboards, does not illuminated on startup having this Logitech Craft is a blessing. I work a lot in dark places and mostly off site. The USB C charging is another plus for a traveler like me as most my peripherals are usb c already. They keys are premium and the body has a solid build. The heavy weight can be discouraging but it makes it much more stable.  The keyboard is very smooth and the travel on these keys are just right. Not too shallow and not too gamer mechanical. Very polished and disciplined. The unifying receiver plus a 3x option Bluetooth profile is very convenient. I have a single monitor with the usb receiver plugged into it and it makes switching from PC to MAC to MAC to PC to PC etc much more efficient with out installing/paring bluetooth profiles. The wheel takes time getting used to but it is a game changer from Softwares I already use on a daily basis.
