I was not happy with this keyboard for one reason...reflective paint on the keys. If the keyboard was used in a completely dark room, it would work great, but the light from my monitor reflects off of the keys, resulting in a very low contrast between the keys and the illuminated letters on the keys. The tops of the keys should have been painted with a matte, non-reflective black, so that the blue light shining through the letters would be more in contrast. In real life use, the visual ergonomics are very poor.I think this keyboard is a great concept, but it was poorly realized. The light from a monitor reflects off of the keys, creating almost a silver look which is very low contrast to the illumination color.I also purchased a small Zippy Illuminated keyboard which is much easier to read. However, the Zippy is only slightly larger than a laptop keyboard and I wanted a full size, so I ordered the Eclipse.
