Ultra Thin Silicone Keyboard Cover Skin Protector Compatible with Dell KB212-B, KB4021, 2GR91 / 4G481 Slim USB 104-Key Keyboard (Transparent)

Oddly, this is the first time I have ever used one of these, so I don't have anything to compare it too, but given how often I eat at my desk and what I've done to other keyboards, I like this thing. It is thin, so not sure how long it will last, but since it wasn't overly expensive, probably not that big of a deal. Feels a little strange, but then I've never used one before. It isn't causing any issues and fits the keyboard well. Easy to clean off and saves having various kinds of food landing on the keys and gumming things up.

Good quality and definitely helps to keep crumbs, drinks, and gunk from in between the keys if you eat at your desk. Recommend this product.

It works well and is easy to clean. It did not last quite a year before it developed splits ans had to be replaced.

It doesn't fit the middle (arrow) keys well. Too wide in that area.
