Excellent keyboard. A long time ago I had a Microsoft Ergonomic Keyboard similar to this one and my wife said that it would take about a week to get use to. I took to it like a duck to water. When it finally died of old age, there wasn't any to be found, so I went with the Logitech Wave. Well it to died, then I found the 4000 Love all the new features like the zoom button and programmable function keys.
Just received my keyboard and happy with the product. Keep in mind, it will arrive just keyboard and batteries; there are no connectivity directions. The keyboard works as new and it is a great purchase. You will have to change the name of keyboard in your preferences after connected, because it will carry the former owner's description. Great purchase, nonetheless!
