Product review (5 stars): Exceeded my expectations!  Would buy again.
Since the reviews were a little mixed, I didn't want to rate these two covers too soon.  Ive now been using them (one for my dryer and one for my washer) for nearly six months.  I am very happy with them.  My appliances are in a shed type structure attached to my house.  There is a screen door on each end of the shed so it can get very dusty during windy periods.  I bought the covers to protect my appliances from dust and dirt getting into the inner workings and just to keep them clean and in good condition.  The covers fit nicely and keep the appliances quite clean.  They are easy to put on and off.  I don't use the zippers but if I wanted to, I wouldnt have to remove the cover to use my top loading washer.  I have also thrown them in the wash to get dust off them and they held up fine.  These covers were not expensive and I think they are a good product and a good value.
