Universal Keyboard Protector Cover Skin for Laptop Notebook 13" 14" 15.6" inch,Ultra Thin Silicone Waterproof Dustproof Keyboard Protector Skin (15"-17.3" Universal Laptop Keyboard Covers)

The sheet works well to prevent dust and accidental lquids from spilling into the keys. But it stuck to the keyboard only for the first two days, after that whatever sticky film that was there had evaporated and it does not stay on my inclined laptop keyboard (just falls off). If the keyboard is flat or nearly flat then no issues. Secondly, the sheet attracts dust and it cannot be wiped away unless washed in water. So, not a enjoyable thing typing on a dusty sheet. I use it only to cover my laptop keyboard while working on an external keyboard , the sheet simply sits on the idle built-in keyboard. When the laptop is shut, I take out the sheet and put it over the external keyboard. So as a best practice, need to wash it every 2 days. Thirdly, the product writeup on Amazon says no crease, but out of the package the sheet as a crease where it was folded and shipped. Even after several days, the creases is very much there and prominent, but does not prevent typing.
