Query: Did not last

The product consists of a tape and plastic. The plastic was a little cumbersome to cut but managable. Once I got the insulation up, it seemed to be working fine. I put it on four separate windows - 3 of them consisting of Duck insulation, and one a 3M product. It is about two weeks from the time I put these up. Two of the Duck insulation tapes have already started peeling off. :(. It does definitely keep the house a little warmer though.
