OK, let me start this again. I have only owned this product for about 4 weeks but I did put it through the paces so that I could give a fair overview. First, I submitted a question about the size of these protectors as I did not know if a standard would fit my pillows. I got no response so ordered both standard and queen size protectors. The standard was a very tight fit. While the protectors measure 20 inches across, on either end the zipper starts at about 1 1/2 inches in so you actually only get a 17 inch opening to put the pillow in. Because of the previous reviews where it is stated the zipper is flimsy, I used extreme caution in putting the pillow inside the cover so as not to break it. There was some air inside but I was able to squish it out with no noticeable problem with air. I did return all of the regular sizes I ordered. If your pillows are as flat as a pancake, then the standard size may do, but otherwise, most pillows today are fairly substantial and normally listed as standard/queen. I reordered the remainder in a queen size and love the fit. I did test for waterproofing and ran water over the case, squeezed it and discovered no water leaked inside. I did not test to see if water got thru the zippered side but then I don't think any pillow protectors would pass that test. Next I laundered the protector and dried it according to instructions. I did not observe any shrinkage (if there was any it was so negligible I couldn't tell). In my experience, the protectors don't cause overheating and I do not notice any noise or excess air between the pillow and the protector once I initially compressed all of it out. My guests have not complained about the pillows which had these protectors on either. I own 6 sets of these protectors in Queen size and would highly recommend them. The only reason they did not get a 5 is because the standard size runs small and the top opening to insert the pillow is only 17 inches, not 20 on both the standard and queen. Would buy this product again and would highly recommend it to others.
