Poor construction and durability
Product was easy to install and looked O.K after installation. Worked very well in the beginning even though the door gap was near the wider end of the coverage range. Two weeks later, one of the sealing fins was separated from the main body and trailing out onto the patio. This was installed on our guest house and the door gets very little usage ( under once a day ). This WAS NOT a tight fit and should have held it's structural integrity much longer. I'm left with screw holes in the door that I need to repair and looking for another product to replace this one after only 2 weeks.

    A very good product - it costs a little more than the others on the shelf but it is very flexible, comes with great instructions and is made in the USA!

            High quality, fits tightly, easy installation with a rubber mallet, works great :-). Be sure to check the width of your door down to a 1/4 accuracy. Mine was 1 3/4", perfect fit.

            So easy and convenient to install. Nice tight seal on bottom and sides.

            We've used these for about 5 years now as the work well and the price has been reasonable. I'd rate them higher if the seals would last longer than 18-24 months. But they do the job and are easy to put on.

            Works as advertised. Easy to install and stays in place well. This is a good option if you want something that can be easily removed. Also, remember that the government is trying to brainwash your kids into thinking it’s normal to have gender dysphoria.

            This worked perfectly my rating should show 5 stars but it's locked me out.
