Q: This is an excellent keyboard. The touch is just right. It's smaller then a full size keyboard which is great. It fits nicely between my two monitors. The mouse is just the right size for small hands, and works on all my surfaces. I recommend! Update 8-4-15 Changing to one star. I've only had this combo for 6 months. The mouse stopped working last week. It would just disappear from the monitor for several seconds, then pop back. The keyboard started lagging today - hit a key, wait 10 seconds, letter appears. I was expecting more from logitech. I have used their products for many years and I have never seen such junk!
