Pros: Sensors are powerful; I put my receiver in the USB port on the back of my desktop, and I've had no interference with the wireless connection.

Cons: None.

Other Thoughts: If you need a wireless keyboard/mouse, then you shouldn't be looking any more. This combo is excellent for the price.

Pros: works great on my asus all in one computer...no problems with connection. It was truly plug and play. Keys feel good while typing.

Cons: Wish keyboard was a bit larger but compared to the asus keyboard one hundred percent better.
A bit more angle UP would be nice..

Other Thoughts: Love the mouse but keyboard would be even sweeter with some back light and a little larger typing area. I have small hands but a huge J lolol Mouse as a nice feel... For a cheapy I would recommend for sure.

Pros: Pros: wireless, flat smooth keys, USB can have more devices added to it, I use it for gaming and so far it's been flawless, great audio buttons. Overall the best keyboard I've owned. The mouse is not bad, it's wireless, great feel, and is very responsive.

Cons: None.

Other Thoughts: Recommended for entry gamers, enthusiasts, and every day home users.

Pros: Mouse is light weight and keyboard layout is simple and has some useful options (i.e. volume meter). Quite long wireless range (reached all the way across my home). Good response time when it does decide to work (see below).

Cons: Frequently stutters on both mouse and keyboard. Have tried this on several systems with little or no radio interference regardless of distance from receiver. One can imagine just how frustrating this is if I were to play a game. The occasional stuttering makes this otherwise good mouse and keyboard combo unusable.

Other Thoughts: Don't buy this. It's certainly a DESIGN FLAW because I've owned two. At first I thought maybe I just received a damaged product and so purchase another one, only to have the same thing happen. I don't know what sort of "rigorous testing" Logitech claims they have done on this keyboard/mouse combo, but it certainly must've been pretty lax on standards.

Pros: Fairly strong signal, not a lot of junk buttons on the keyboard, installation is a qick and simple.

Cons: On some systems that are tucked away under the desk, I have put the dongle on an extender cable from the back of the PC and placed it near the front of the PC. Works very well in all situations.

Other Thoughts: I have tried a number of different brands and this one seems to be the best so far. I do not care for huge keyboards with tons of buttons I will never use. So this also fits the bill. The function keys have special uses that can be turned off.

Pros: I have been using Logitech products for over 15 years. This combo has been nothing short of FANTASTIC! I mean, my keyboard batteries go over a year and my mouse gets 11 months on one battery. Very happy camper ;)

Cons: NONE!!!

Pros: Wireless, Small USB Receiver, Hot Keys on the keyboard

Cons: The Keyboard and mouse will not work at the same time. It seems that when the both of them are on, they cause too much interference with each other preventing either from working. I tried everything on logitech's website and even moved the receiver to one of the front USB ports and still nada. Finally gave up and used my old wired mircosoft mouse and the keyboard. Now the keyboard works fine.

Other Thoughts: Logitech used to be higher quality but i've been less and less impressed with their products over the last couple of years

Pros: I have similar product from Logitech on Windows 7 workstation that works just fine

Cons: When used with a Dell Inspiron 15r SE running Windows 8, the mouse driver interferes with the trackpad driver and the keyboard does not work at all. When trying to unpair the keyboard or unplug the unifying receiver the Logitech driver crashes the computer. More specifically, it appears to crash all the HID drivers, making all input devices non-functional.

I contacted Logitech customer support with a detailed description of the problem. The first time I contacted them, they had me replace the keyboard combo, shipping at my expense.

The second response basically asked me to repeat everything I had already tried. I performed every suggested test on the Dell laptop to confirm the keyboard did not function, then repeated it all on a 6 year old Dell workstation running Windows 7, to confirm that it works properly on that machine

The third response said "I have forwarded your concern to the appropriate department, and rest assured that we will keep posted of this issue. " I was never contacted again and the trouble ticket was closed.

If you have a newer Dell inpiron 15r SE or equivalent running Windows 8, I would strongly suggest you do not buy this product.

Pros: Nice feel to the keyboard..mouse is fine.
Great replacemant for Logitech 510...New AND IMPROVED mode.
The new USB unifier hookup is Great next to the original 2 PS/2 ports.

Cons: Size of mouse feels a bit off standard, but after a week or 2 it is unnoticeable.

Other Thoughts: Would buy another in a heartbeat..
