I have purchased several of these types of gates over the years for pets. This is one of the best gates I have ever had - very good quality, sturdy, easy to open and close. It also has the function of staying open when pushed past a certain point and it ACTUALLY stays open. Really nice feature. The adjustable cat door is nice, but be aware that it does rattle. With that in mind, your cat WILL rattle that bad boy when their food dish is empty. At 2 AM. Just sayin'.It installs very easily and sits securely in the doorway and really doesn't budge once it's in place. I have bumped into it several times and it hasn't moved.The only potential issue is that this is a "tall" gate which means it is roughly as high as your average doorknob. I have a gate on a door with a regular "ball" type knob and one on a door with a handle-type knob and both hit the top of the gate, preventing you from being able to close the door fully. Additionally, the part of the gate that impacts the doorknob is the stationary side piece, so even having the gate open will not allow you to fully close the door.Not a terrible issue, but one to be aware of. I have had the shorter, "regular" height gates and they end just underneath the knob and you can close the door. Just an FYI.Overall, a very nice quality gate that works well.
