The Ultra Classic is our BEST keyboard. It's built with the same buckling spring mechanisms, keybuttons, and steel baseplate as used on the Classic. The stair stepped keys, tactile "clicky" feel, and robust design are the same as well. It's Ultra because it uses a newly designed clamshell cover set reducing the footprint by 20% and eliminating almost ½ pound of plastic.
A quiet touch (rubber dome) version is also available for customers who want the heavy duty design without the audible "click" and tactile feel of the buckling spring version.
