I think this door sweep is very well constructed and does the job when installed properly. It cut nicely with a good hacksaw. Here is my problem: I drilled pilot holes in the door and then screwed in the supplied mounting screws only to have the screw fail...head tore right off. I had to use screws from a much cheaper brand of door sweep to mount this. I would've given this product a 5 star rating had their quality extended to the supplied mounting screws.
