Bests & Worsts Reviews from Amazon

I have been in the IT profession for 31 years now, and this is the best unit I have ever used. I have been using this combo unit for years, and love it. I am currently on my 2d combo unit, and getting ready to purchase my 3rd combo unit. PROS: Battery life. The batteries last longer than the imprinted characters on the keyboard. I have had my current combo unit 2 years, and the battery charge window says I still have a full charge. I'm using Duracell batteries. Mouse: I love the 'back/forward' keys on the side of the mouse. You won't ever have to use the back/forward arrows on IE or Firefox. Durable: I have spilled multiple things on it, and it keeps on working. Keyboard: Smooth, and easy to find keys/buttons frequently used. CONS: The imprinted characters don't last long. So, if you don't have your keyboard layout memorized, you'll either have to keep replacing the entire unit, or, buy a character replacement stick-on kit. Mine is so worn out, the characters have been worn off, the space bar is now smooth, but at least the dents on "F" and "J" are still there to easily find "home row".
