I have to give this product a bad review. It had one job, and that was to shield the keybed from dust, but this piece of cloth sheds so much hair that it might as well be a dust sprinkler. This totally defeats its purpose. I will try to wash it in my washing machine and hope it'll get better. €40 is already crazy expensive for a small piece of cloth, you'd think it would actually protect your keybed from dust instead of adding its own "dust". I'm very unhappy with this product and I regret buying it. It looks nice though.
