Very well-made, but instructions were a little confusing took a few times to figure it out other than that it’s a great purchase for me

Looks nice, the instructions are terrible though and two of the drill bits snapped like nothing. Holes marked as pre-drilled were not. It'll work fine, but not worth the price.

Excellent pet door insert for sliding door! This pet door is very well-made, sturdy, and easily assembled. The flap is thick and has magnets that are solid but not too strong to keep our cats (ranging from 13 to 19 lbs) from going back and forth for their catio that lives outside the slider door. My husband did add some weather stripping on either side, but that is entirely due to our home and doors being older and smidgen wonky. Highly recommend!

My pups are loving the sliding door insert. It was super easy to put together and install. Seems like it is made of quality material and I love the fact that the safety shield can just be lifted and doesn’t have to be removed each time my pets need access.
