I had one at work and it's an extremely great keyboard. I combined it with a Logitech Expert Mouse (actually a trackball) and my shoulder/arm pain was better within a week. I have an Ergodox EZ at my new job and it's good but I'd recommend the Kinesis Advantage 2 over it if someone asked. Same price.
