Acrylic Dust Covers - Do they change the sound

I was looking at the dust covers offered here on the Gon by 1854k and was wondering if they change the sound of the table in any way. They look nice and I hate to dust my turntable, (Aries 3) every other day so I would like to have a dust cover for it. I also would like to provide more protection for the tomearm/cartridge when not in use. They look nice and are a lot cheaper than the others I have found but what about the sound.
