This does not support unifying receiver.

Stay away from this product unless you are sure you won't lose or accidentally break receiver or not prefer the convenience of a unifying adapter.

The wireless receiver was missing in the first package and I reported it and requested for a replacement

Works well but no unifying receiver.

Con:Might observe lag if the receiver has obstructions

Replacement 'unifying' receivers from Logitech do not work!!!

Does not use the Logitech unified receiver, so it won't automatically work with my mouse/keyboard at home.2

the USB receiver stops working correctly, and becomes very "glitchy" where the mouse skips inches across the screen and also becomes unresponsive every couple of seconds

* Good Reception (receiver located in the attic directly above the room)

It works, but the nano-receiver is NOT compatible with the Logitech unifying receiver.

The receiver worked to recognize both the mouse and keyboard but no personalization was possible.

This is a great keyboard and mouse setup, but the receiver is absolutely terrible

The receiver that comes with the product does not have the Unifying logo (first clue) and the keyboard and mouse do not work with a Unifying receiver (if you have one).

However - NEVER LOSE THE USB RECEIVER.

If you drop your computer and break or otherwise lose your receiver, you cannot get it work with a unifying receiver.

The receiver only worked with the keyboard - not the mouse

Unfortunately, the unit arrived without unifying capabilities, requiring me to plug in both my existing receiver for my mouse as well as the regular nano receiver for my keyboard

I'm not sure if I just got a faulty receiver but either way it is very annoying.

That means that if you lose the receiver, you must buy a new keyboard and mouse.

Receiver somehow got damaged, so I thought I'd just get her a new Unifying Receiver, which works with every other Logitech product under the sun

Next up, it's not the unifying receiver (bad on me for not paying closer attention).

It did not have a universal receiver (it was missing the orange

One receiver will only work with one mouse.

I think the receiver got some problem

I'm not pushing the limits of distance from keyboard to receiver

I just wished the receiver was better on this model

The only caveat is that employees have to be smart enough not to lose the receiver or get it mixed up with other mice or

I think the receiver for this set is the problem

This product arrived missing the usb receiver, making it pretty much useless

The new receiver for the keyboard is terrible and drops out and stutters constantly.

: Great for price, mouse is extra sensitive, single unified USB receiver for both mouse and keyboard, range could be better

In the past several months the receiver stopped working rendering it useless.

The receiver is about six inches away from my keyboard and mouse, and it lags constantly

Bought it to use with my Raspberry PI but after couple of months of use the nano receiver got loose

The wireless receiver died in less than two years

Great keyboard, be careful not to lose the receiver.

On top of that it's missing the nano receiver

The receiver does well when plugged into the USB ports on the front of my case, but connection lags terribly if in any of the ports in the back (about another foot

Does not support the unifying receiver
