Query: The best on the market but...

I've used this product many times and it definitely does the job of keeping the cold out and the heat in. My heating bills show a major difference and that's my main goal. This brand is better than other brands because the plastic is sturdy. Here are my complaints: First of all, when you blow dry it tight, the tape doesn't stay glued. Also, it never blow dries smooth enough, even when I know I got it up straight. So I don't bother blow drying at all anymore. I can see through it just fine and I've gotten used to seeing the wrinkles. Oh yeah, the biggest pain in the butt is getting the backing off the tape. Not good! But I'm ok with it overall because I'm toasty warm. :)
