PetSafe 4-Way Interior Locking Cat Door - Allows Convenient Movement Between Rooms & Minimizes Scratching - Tinted Durable Plastic Privacy Door for Feeder & Litter Box

For the low price of this door, $8, I was halfway expecting no so great of a product. I thought I might as well try it and replace it later if it didn't work. We had a pet safe model cat door at our old house, and when we moved I tried to but the same thing.I'll admit I must have been distracted or something when I bought this, because it thought it was for exterior door use. It is not. But that is clearly included in the description. My fault.Since we moved our pets to the new house before we lived there, we needed a way for the cats to get inside for food and to be out of the elements. I realized my this product is for interior doors but installed it anyway on the exterior door to our garage. It's has been on there for eight months now, and functions so well I don't wish to change it.What makes it for interior doors only is that it is missing the piece in the middle which covers the exposed inside of the door that you cut a hole in. I Cut a strip of Formica that I had and put it in the middle of this cat door to keep the rain and moisture out of the inside of the door. So far this has worked great.As far as I can tell the build quality and materials used in the interior door are the same as the exterior pet doors. Well made thick hard plastic sides and hinged door. It swings open easily and has the ability to lock if you feel the need.Obviously I don't recommend anyone to use this inside door on the outside door, but my point is that it is very well made and durable. Not a different flimsy grade or anything because it's meant for inside.The magnet is holding up great, I have had no problems with it falling out as a few people have mentioned. We have two cats that go inside and put quite a bit throughout the day and night, so I know it gets quite a bit of use.The instructions are easy to understand, they tell you exactly what you need before you get going so there are no surprises. There is a bit of overlap in the pieces so in case you are not perfect with your cuts it will not show when the door is installed.

Bought the two-way locking version. Not a fancy door, but very inexpensive for the quality. Called PetSafe with selection questions and was impressed with the US-based support.Would have been nice if they included some sort of lining rather than suggest the use of duct tape, but I was able to 3D-print a suitable flange. Ever so slightly noisy, but that was fixed with a little bit of silicone lubricant. Ball bearings would have been a nice upgrade but would have added to the cost. Included screws were apparently sheet metal and not wood screws per my tradie but they worked fine. The double-sided tape had a little thickness that left a visible gap, took these off and clamped with a bit of solvent glue for 24h for a cleaner look.Don’t think I would have gotten close to 5x the value out of a door costing 5x as much. A little fussy but you get what you pay for and a little extra work makes it an even nicer product.

I would've given this a 5 star review, except for the fact that the instructions are only pictures. While they are easy to understand for me, I loathe pictures in instructions because they aren't even really well-drawn.Now that I've said that, I borrowed a jigsaw from my dad to install this in a hollow-core door I found on the side of the road. I was hesitant at first because the last cat door I bought that he installed on a hollow-core door was a pain to install. The template was incorrect, so we ended up having to recut and wing it. This one, however, was exact. (The template is what the instructions are printed on.) I traced the template, drilled the holes on the corner (inside the template), then cut it out with a jigsaw. I then got a small drill-bit and drilled starter holes for the four screws that go in the front corners.In total, I spent maybe 10 minutes total, including going back inside to get a different drill bit.The instructions did not mention starter holes, but I wasn't able to just screw these in without the holes. They also didn't make it 100% clear that I had to drill INSIDE the template to start off before cutting with a jigsaw, but after looking at it for a second, it became clear. I had just assumed at first that was the starter holes, but it was not. (Judge away...I've never done this sort of thing before.)The locking mechanism is also really easy to use on this door. However, I can see it being TOO easy...I could see it latching accidentally, but it's not that big of a deal for me, as she will just be going in and out of another room, vs going outside.Also, heads up, the flap does not have a seal so I would definitely not install it on an exterior door.The only down-side to this door that I do not like is that the screws only go in through the front. The back part of the door is stuck on with stickers that are included. That seems very cheap, but it serves it's purpose and my cat is on the small side (8 pounds) and she doesn't mess with the door or try to ruin it. I don't use it to lock her in a room either, so she doesn't claw at it. The door is just so I could install an actual door on my laundry room since it is not insulated, and I'd rather keep the litter box smell isolated as much as possible, and keep my small kids OUT.

The set up was super easy. The plastic seems durable. I put it on me door and I noticed that two sides don't attach (door or not) with an adhesive tape which has held up so far. Locks pretty well and my kitten understood quite easily so I'd assume it's not hard to open. Overall great purchase!
