Door insulation
Easy installation works great

Great bottom door seal.
This is a very good bottom door seal. I would recommend that you use a wooden block to hammer the weatherstripping into place as it will slide in much easier than trying to do it by sliding with your hands. The bottom seal fit good and tight. No more drafts under the door.

Works well, easy to install
Works very well. I had a very drafty gap under my front door. Removing the old metal kick plate and replacing with this took only a few minutes. Mostly to trim it down to the right size. Also installed one on the bathroom door to prevent hot shower air from leaking out during a bath.

So Far, So Good
So far this seems like a good replacement for the factory weather seal.

Worth it
This is so much better than the stick on draft blockers I tried for years. They ALWAYS fall off and are just a waste of time and money. I had a considerable gap under my back door, maybe close to an inch and the cold air whooshed in all winter. I got this draft blocker and it is extremely snug on the bottom of the door. I suggest thoroughly cleaning the door and then priming this with a little silicone or olive oil, whatever you have. I had some sticky stuff left over on one spot and it was a bear to get past. I used a hammer on the end and some dish soap and finally got it on. The door was initially harder to close, part of it was it wasn't quite on all the way. I adjusted it a little more and it was much easier, but it isn't like it was before. I have to give the door a bit more of a push now, which is fine considering the dust, bugs and I suspect mice that creep in in the winter the moment it starts to get cool. Worth every penny and I wish I had gotten it years ago. If it breaks down over time (as literally everything does... I will happily replace with this item.

Good seal but breaks after a few months
I've had this on my garage door for about 3 months now and the pieces that seal the bottom are starting to break off. Originally I really liked this item because it was very easy to install and didn't require any screws like our old one. It also seals the door very nicely! Our floor is uneven so we thought the little plastic pieces on the bottom would be a good idea but it seems it seals the bottom so good it's causing them to break off.

Altamente recomendado. La pieza llega de un tamaño estándar a lo largo en el que se puede ajustar al tamaño de la puerta donde se desea colocar. Es fácil de cortar a la medida deseada y, una vez colocada en la puerta hace un cierre hermético que no permite el paso del polvo. La instalación en la puerta es superior sencillo.

Es muy bueno, ayuda también con el ruido y sin problema lo pude cortar con un cuchillo.

Installed 10 days ago. Easy to cut its length. Stays in place. Tight for our gap - makes swinging the door difficult. But it stopped the air coming in.

Fits the door and easy to replace old one
