## Customer Reviews

### ⭐⭐⭐⭐⭐ Easy installation
*by A***K on December 8, 2025*

This worked great to attach to my Pet door. 4 inches in height made a world of difference for my big dog to go in and out of the door.

### ⭐⭐⭐⭐⭐ It works as advertised
*by B***N on July 6, 2025*

Fits perfectly and provides the extra height I require

### ⭐ Cheap and useless
*by J***N on June 10, 2025*

Cheaply made, the holes for the screws do not line up with the holes on the door. The only way to install this on the bottom of the door (below the flap) is to install it upside down, so there is no way for the door to stay in place on the sliding door track.
