The ProTouch FX fits a MacBook keyboard well, but I was disappointed by the feel of the cover. If I pressed directly in the middle of each key when I typed, the ProTouch FX worked fine. However, the sides of each individual key cover are more rigid than on any other skin I've tried--rigid enough that if I pressed a key off-center, the key often didn't register. Over time, I was able to adjust to this behavior to some extent, but never completely.

KB Covers Checkerboard and Clear Keyboard Covers

As you might infer from the company's name, KB Covers specializes in keyboard covers, producing basic, protective covers for every Apple keyboard, as well as foreign-language covers, covers with keys labeled for specific programs (for example, Photoshop or Final Cut Pro, or World of Warcraft), covers with large-type labels, and even for those learning to touch-type.

I tested the MacBook versions of the company's and , each $25. Specifically, I tested the Ice model of the Clear (model CV-M-Clear), and the Checkerboard version made of clear silicone with black keytops and white key labels (model CB-M-CB). The Clear is also available in transparent blue, green, pink, and purple silicone. The Checkerboard also comes in clear silicone with white keytops and black labels, and in clear silicone with black keytops and white labels.

Both covers fit the latest MacBook-style keyboards well, although, as with the ProTouch FX, the sides of individual key covers are fairly rigid. I didn't have nearly as much difficulty typing on the KB Covers models as I did with the ProTouch FX--the KB Covers covers didn't cause me to mistype--but both the Checkerboard and Clear gave my keyboard a noticeably different feel.
