Product Reviews
Lenovo Natural Ergonomic 4000 USB Wired Keyboard is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from This is a split natural keyboard. It's well worth taking the time to learn to use a split keyboard. Typing is smooth and quiet, and the keyboard feels very solid. The programmable buttons save time opening commonly used applications, and the key to open calculator is a great idea. I'm hard on keyboards, so they typically last me about a year before I get a new one. I'm now on my fourth keyboard with this layout. The first three were the 9000, but I'm now using the 4000 since they no longer make the 9000.
