## Customer Reviews

### ⭐⭐⭐⭐⭐ Works exactly as promised.
*by L***S on November 10, 2024*

Wonderful keyboard. They wear out and last about two years.

### ⭐⭐⭐ Nice but not what I needed
*by A***X on September 7, 2024*

Love the keyboard, trackball needs a right/left hand option.

### ⭐ Lost productivity. Not worth the money
*by S***H on June 30, 2019*

This keyboard is very cheaply constructed for one costing close to $100. The keys clack noisily and some are hard to depress causing numerous typos because certain keys require a harder keystroke than others. This slows down and disrupts the typing process and requires numerous edits to complete jobs, which negatively effects productivity. Definitely not worth the money. I kept hoping I would get used to it and alter my typing style to make this work. But it I went back to my $30 wired keyboard after just 3 days. Too many typos and lost productivity.
