Impressed with the quality of this item especially for the reasonable price. Works perfectly and the brown color is great - it doesn't call attention to itself in the bedroom door where I installed it. The template and instructions were good. The only reason I didn't give it 5 stars is that it's made to "self line" but only up to 1/2", which is way thinner than standard for residence interior. So if you have a hollow door, you have to improvise something to seal it off. I played around with flexible plastic but ended up just using duct tape, which has been working just fine for over four months now. If I need another cat door at some point, I would look for another one just like this.
