## Customer Reviews

### ⭐⭐⭐⭐⭐ Half inch gap is too tight for the door sweep.
*by D***. on June 5, 2025*

Excellent quality and recommend, but the door to the floor in the photo is a 1/2” and was too tight and won’t work. So I tried a door that was a heavy 9/16” and still too tight.5/8-3/4” would work nice. Not going to trim doors. Check the opening size and order, did think if one of the door sweeps was removed might work on the 9/16” gap but moving on to a different style door sweep.

### ⭐⭐⭐⭐⭐ Closes the Gap! Cuts the Light: Blackout!
*by N***L on April 8, 2025*

Excellent Solution to Close Large Gaps Under Interior Doors!Interior doors seem to have huge gaps to the floor these days, and in my case, the gap below the en-suite bathroom door let in so much natural light from the bathroom window that the whole bedroom was lit up.A standard single-sided, screw-on solution could not cover the gap, even after drilling new holes near its top edge.This slip-on (more like, “Push like heck”) solution literally fills the gap. It extends to the floor on both sides of the door, doubling the number of barriers to the passage of light and drafts.It’s also infinitely adjustable by just pushing it down to the floor where necessary, or lifting it up to clear higher flooring surfaces.The compression fit means no damage to the door from screws, and the ability to adjust the gap anytime as necessary. You can then take it with you at anytime, leaving no damage to the door.I bought and installed two, and with the window covers I’ve recently added, my bedroom is now so dark - near 100% blackout - that I’m sleeping till Noon….(Good thing I’m retired…!)Highly recommended!

### ⭐⭐⭐⭐ Good Product.  Lousy shipping.
*by J***F on May 20, 2025*

The good: Well made product that does what is says it will do. Flexible for different types of doors. The not so good: Horrible instructions. Please start shipping with Amazon. USPS took 11 days which is ridiculous for a product that should be here in 2 days tops.
