Summary: I did my homework before buying this equipment. I had been using the newer, more expensive version MK700/MK710. After extensive comparison on features and capabilities, I settled on trying this one. After several weeks of using them, really wish I'd have bought this one the first time around.
Summary: This is the 3rd Logitech Wireless Wave Combo that I've bought! I keep one at the office and one at home and got the 3rd as a gift for my sister. No problems and they work great! Love the feel of the keyboard - not as ergonomic as my older version, but it still beats the flat keyboard for typing!
Summary: I bought this to replace the earlier version of the same thing. After years of use the mouse had become erratic and the keyboard was a little sticky. I like the new unifying receiver that gives the option in the future to add or replace the mouse or keyboard individually.
Summary: Worked great right out of the box. However, if you want to use ALL the keys you have to download the keyboard and mouse driver that you can find on the Logitech link. You will want to do this if want to know whether the Caps Lock is on or off. The keyboard has no indicator light for this.
Summary: I have bad wrist and with the wave shape of the keyboard, my wrist do not hurt me as bad as is did with a regular keyboard. I can play my music with just a hit of a button. Turn the volume up or down with buttons on the keyboard. I like that it shows the battery life on the keyboard.
