I have had this keyboard and mouse for well over a year and it is still working great!! I have had NO problems with it and it was so inexpensive. It is the first wireless keyboard and mouse that I have used and I am sure there are more expensive/sophisticated ones on the market today, but this product has performed perfectly for my purposes and I am online practically eight hours a day and do surveys and play Facebook games and I have only replaced the batteries about four times. Performance Couldn't ask for more!! Durability Still going strong!! Design Great for my needs! Comfort Absolutely, can use it tilted or flat.

Purchased the Logitech S520 Cordless Desktop for my home office back in March of 2010 to replace an old wired keyboard and mouse combination and I have been satisfied with the overall look and performance of the S520. The Good: First impression was good, the keyboard is slim and compact which makes for a small footprint on my desktop. There are preprogrammed keys on the keyboard that allows for one-touch access to media on your PC. There are also customizable buttons which allows you to program shortcuts and macros for power users, which is a bonus. Buttons feel good and provide good tactile feedback when pressed. There is also a 10 key for quick number crunching on the go. The mouse has good battery life, and Logitech's laser technology makes cursor movement and tracking smooth and accurate. The mouse wheel is also customizable and you can set functions like 'back' and 'forward' for easier web navigation, and I like setting the wheel so that when I push down on it, the current window is closed. Very convenient. The Bad: My biggest complaint is the USB receiver, it is just too large and obtrusive. It would have been much better if the receiver was a micro receiver and less conspicuous. Another thing Logitech could have done was to have made the keyboard backlit. But considering the price, the S520 is fair in its offerings. All in all a decent wireless combo which frees up clutter on my already messy desk, so 7 out of 10 from me.

We use this hooked up to a broken laptop that is wired into our TV for streaming Netflix. The cordless desktop allows us to sit on the couch 6-8 feet away and control the Netflix. It's perfect for this use and the range is much better than we expected from a wireless keyboard and mouse. The mouse is also really versatile, as you can pretty much use it on any surface -- the couch, your knee, whatever is handy. Great piece of technology!

So after using this keyboard and mouse for a long time I have to say I am very happy with it.  The range was suitable for use for a home PC if you ever feel like sitting away from the desk or hook up your PC to the tv and veg on the couch while surfing all the while.  The layout is the new type where the page up/down keys are no longer in a horizontal row but vertically placed so if that bothers you as I know it does some who prefer the old layout this will not be for you, but if you can adapt the keyboard does wonders for the wireless lovers.  The keyboard other than that has the usual layout so no surprises for other key arrangements.   Like most keyboards today they have functional keyboards preprogrammed for things you would see on the laptops with a function key and special key assigments such as Microsoft Word or e-mail or Excell etcetera.  The keyboard and mouse work nicely though I do have some problems with the usb receiver if I orient it in different ways the signal is not caught by the keyboard for some odd reason and has to be oriented to point directly out to the user, unlike some other wireless Logitech accessories I've used in the past.  The receiver is also quite large so don't expect a small adapter that blends into the side of your laptop or keyboard.  Overall though the price was good and works well from across the room.

My 5 year-old daughter learned to use my PC.  Unfortunately that was the kiss of death from my Microsoft multi-media keyboard and Logitech PS/2 mouse.  The problem was they were both wired input devices and just could not stand up to the abuse of a 5 year-old.  They died a slow, painful death.  So, needing to replace them, it was imperative I find something that would meet my needs and wouldn't have the cords continuously stretched to their limits by the one herein referred to as, "the kid". Fortunately my needs are not many and that's a good thing.  For some reason, manufacturers make mice and keyboards ranging from very basic to "does everything but wash the dishes".  You can get them ergonomically designed, all different shapes and with special buttons that make you afraid if you push the wrong one you might launch nuclear weapons on Iran.  Now, I'm sure there are folks out there who appreciate all those bells and whistles, but I'm a simple man (no, I didn't say "simpleton") who just cruises the internet,  runs OpenOffice and plays a few computer games. No rocket science for me, so I don't need a keyboard or mouse that allows me to do that. Thank you, Logitech for the **Cordless Desktop S520**.  Here's a desktop combo that's not only affordable, but is easy to set up an use.  In fact, I didn't even need the included software, although the SetPoint software has many useful functions.  With Windows 7, I just plugged them in and my operating system found them, installed the drivers and we were ready to go. IN THE BOX: 1 flat cordless keyboard 1 laser wheel mouse 1 USB Receiver 4 AA Batteries The keyboard and mice installed easily by plugging the receiver into a USB port on my PC, then inserting the AA batteries, two each, in the keyboard and mouse.  On the back of the keyboard are instructions for getting the wireless devices working by pressing  a button simultaneously on the keyboard and receiver then on the mouse and receiver.  I didn't have to do either of those things.  As soon as I turned them on and rebooted the computer, they worked.  Just like that.  Sweet. The keyboard itself is flat with their "Zero Degree Tilt" flat design and large, well labeled keys for easy typing.  This, along with the nice curved wrist rest make typing, indeed, easy.  My last keyboard had raised keys and no wrist rest which forced me to keep my wrists in the air and this made my arms tired more quickly. The keys are VERY quiet and press easily. Along the bottom are several useful keys.  On the left  at zoom keys that let you quickly. Also, there are keys that will control the volume on your PC, a low battery indicator light and, along the top buttons that will turn your PC on/off and one that will launch your calculator. Using the included SetPoint software, all the function buttons along the top are programmable to launch Word, Excel, email, calendar, and various other PC programs.  This could come in handy for us lazy people who don't want to reach over to the mouse and find the program on our desktop. The mouse is designed to fit the normal hand (and thus could be a little small for any ham-handed folks out there).  It has 3 programmable buttons and a tilt wheel.  I found it very smooth, comfortable and easy to use.  Powered by 2 AA batteries and directed by a 1000 dpi laser, the Logitech wireless laser mouse also has its own on/off button. **THE BOTTOM LINE** **Logitech's  Cordless Desktop S520** is an excellent low-profile, high performance keyboard/mouse combination. So far, the wireless has worked flawlessly. The keyboard is easy on the wrist and the fingers and the cordless mouse is responsive, accurate and comfortable.  If you are looking for something not too expensive but that meets your basic PC needs, this desktop set might just be perfect for you.  In truth, Logitech has made PC peripherals superior to Micrsoft's for some time.  This is no exception.  I've been a Logitech man for a long time when it comes to keyboards and mice because, while Microsoft brings the name, Logitech brings the game. Plus, no cords for "the kid" to destroy.  **GRADE: B+**
