Summary: I have three of these keyboards. One at my workstation at work, this one is 1.5 years old and works as good as did out of the box. I have one on my gaming rig at home and it is just over a year old and it still works just as good as did it did brand new.
Pros: Inexpensive. Keys spring back up quickly, scissor springs under keys, feels great on the finger tips. Feels sturdy.
Cons: Wish the keyboard was a little larger, I have big hands.
