These are my opinions about the chess clocks that I own. I cannot get this page to process correctly.

## My use case

Every review and reviewer has its biases, and I am sure that this one is no exception. I purchased the Centaur computer with a particular set of uses in mind. Therefore, my impressions of its performance will no doubt be colored by these expectations. In an attempt to provide a little context for my comments that follow, here is what I was looking for in a personal chess computer.
