Review on Ultimate Sneaker Protector: Yellowing Prevention, Travel-Friendly - 10X17Inches by Falcons Berry

I've bought this particular brand of shrink wrap a few times and only a few sheets were "defective". Problem with diagonal seam. This last batch had a few tears along the seam leaving small holes. I have nothing against black leather/synthetic shoes, but it's utterly useless when shoes can turn yellow from that point of impact. I would say that in a normal batch there are 5 to 10 sheets with defects. I give it the benefit of the doubt because I may have used too much heat or something else on my part. With this batch I don't even have 30 sheets and I had over 10 sheets torn at the seam. Big disappointment! I hope it's just a quality control issue and this batch just sucks but they get a rating that reflects that.
