Well made product, good weight and holds well in to the door. Make sure the dimensions are correct with your door before you buy though. You won't be able to adjust/customize.
For small items like this, you want to install them and never have to think about them again. This door sweep hits the mark - it is easy to install and works like a charm. The installation was very easy, although with my metal apartment door it took longer than expected, but still under 20 minutes. It squeaked a little when first installed (the entryway is not level since it is an old building), but that went away after 2-3 opening and closings.
Overall, very satisfied with the product, will see how long it lasts (expect it to be a long time since it is very durable).
