Review on Frost King B79 36H Slide: The Ultimate Solution for Effortless Window Insulation by Tim Toscano

I spent the money to buy two of these. They both broke when I tried to cut them. I then attached them to both doors and neither door even comes close to trying to close. I have about a 3/16 gap in both doors. I don't see anywhere that they require a minimum clearance to work. Now that they're both circumcised (my fault I think) I can't get either of them back.
