I have a real all Silver Vapor Pro Spectra. I have also had a fake all Silver Vapor Pro Spectra and an all Silver Chroma, both from China.
The Silver finish on the real Vapor Pro has a very high quality, shinny brushed look. It is very similar to the stainless silver finish on the antenna band of the iPhone. The edges all have a smooth feel in your hand and the overall feeling of the finish is much smoother than the silver fakes.
Compared to the real all Silver Spectra, the fake silver is flat and dull looking. The edges have a slightly sharper feel like they skipped an edge de-burring step before finishing. The Spectra finish is supposed to be shinny, but the Silver on the fakes looks much more like the duller finish you would expect with the Chroma finish.
The fake Chroma finish is actually even a little duller and a little lighter silver than the fake silver Spectra, but they are very similar. The fake Silvers have a finish that looks like the finish on a Mac lap top, much many people seem to like.
