Summary: Comfortable feel. Good arrangement of keys. Multimedia buttons (play/pause/volume) are conveniently located. Battery life is good. A very solid keyboard overall. To the reviewer who had problems with the mouse not moving and the keyboard being unresponsive -- if you have the receiver behind high EM equipment or anywhere else the wireless signal can be impeded this will happen. If you reposition the receiver the problem resolves.
Summary: This combo of mouse and keyboard seemed nice but they start to not respond well, especially the mouse. It doesn't respond to being moved on a desk or mouse pad at times. The keyboard sometimes doesn't respond with quick typing or doubles up on the word.
Lasted less than 2 years like last Logitech keyboard
17 January 2012
Summary: You'll find lots of complaints about keys wearing out prematurely on these. This keyboard is rubbish! It was a replacement for my last Logitech keyboard which also died after 18 months, so not impressed with Logitech products
Pros: Worked OK initially, Built in wrist rest, Nice mouse shape
Cons: Some keys started getting sticky after about a year, eventually needing several hard jabs to work (& yes I tried cleaning them), Sender on the end of a cord adds clutter to your desk
Summary: I purchased this wireless keyboard/mouse combo because my keyboard from Compaq was sticking. This is the most silent and best feeling keyboard. Really increases my typing speed due to the soft touch of the keys.
Excerpt: The Logitech Cordless Desktop S520 is a keyboard and mouse combo. I honestly love this product mainly because I was upgrading from an old Emachines keyboard and and old Gateway mouse. Even though I love this product there were downsides, but I’ll get to those in the end.
Summary: After a few years of daily use this set is still working well and only ever needs batteries replaced. The letter on some of the keys are worn out but it used every day so this is to be expected I guess...missing my L, O and most of my A! Apart from that this is a great set and worth the money for sure!
