Query: Review of the Kensington Keyboard for Apple Mac Computers

The second Kensington keyboard that I've purchased to replace the original Apple keyboard. The previous Kensington keyboard was working fine until I attempted to remove keys to clean them, following on line information. I was pleased with the prompt delivery of the replacement keyboard.By the way, I found a good product for cleaning the keyboard keys at the local Radio Shack store.
