now I might be biased, but I love this plastic. how does it work in the gun? TERRIBLE. but that's not how I'm rating it. I use this product DAILY. and I've bought this plastic roll kit over 6 times now. I tape off windows and usually you have to tuck the plastic behind itself to get a good tape surface. this make my life 10X easier. I cut it to size using a utility knife, then just unfold whatever I need, no more tucking plastic!!! yes, it's way overpriced compared to the 12' x 400' rolls of plastic. but the folds, and the size makes it extremely easy to use and more than well worth the money. I own a business in air sealing houses, and we have to tape all the windows in the house, so they are airtight. we start the job at 8:30 and end at 3:00, but for the days that I have multiple houses I have to air seal in a day. this plastic is TWICE as fast compared to a traditional roll of plastic and can save me from 30-80 minutes a day and that saves me money from paying my 2 employees $20 an hour.
