First of all, the color is very difficult to call silver, it is rather a light gray with little glare. Anyhow I was looking for something light colored and it suites me well.
My keyboard is 95x38 and it looks that cover in length and depth is just a little bit over stretched. It stretches well, but the more tension the more you can see what's under it. My Casio is white and silver, so for me there is no problem. Probably dust protection also decreases with greater tension.
The seams, prints and elastic drawstring look good.
After unpacking rinse it with softener to get rid of smell and wrinkle.
Verdict: nice looking cover, decent quality, suites best up to 93x35
