I'm not the handiest person, and my circular saw is cheap and small, but installation was still very doable- took about 30 mins. The hinge is not super heavy duty, which is fine for our home, but if you have rambunctious toddlers or something it could be an issue. Overall a great solution to maintain privacy!

Excellent product

I installed this product on two of my interior doors - excellent product. Easy to install… instructions were accurate! Our cat started using them immediately without hesitation. Very good experience!

I love it and so does my cat!

I feel the kit is expensive for what it is, but it works great! This is the second one I bought as my original one was damaged and stopped opening probably

Good- cat size?

It is easy to use. The only problem seems to be that my cat might at out grow it, as she is a medium to large breed. So for larger cats you might consider moving it further up then instructed (if possible).

Easy to install. The cats had no problem adjusting to the new way to get through the door. Very clever idea.

Huge Blessing!

So easy to install and get on the door. The template and video steps were clear and easy to follow. It relieved a huge problem with sleeping. Our kitty loves it and so do we.

Great idea

Definitely beats having to leave door open or having to make my cat go through a flap.
Pretty simple install

As easy and perfect as I hoped!

The instructions were very clear and easy, all the parts were there, and the whole setup took less than an hour! Very, very pleased. Be aware, your kitties may avoid it for the first few hours, because the door they're familiar with will suddenly smell like sawdust lol. My kitties got used to it and started using it after an hour or so.

Kitty Corner - Does the trick.

So I actually bought two of these, one for the bedroom and one for the laundry room where kitty's potty is. After cutting the door and installing the bracket, I had a couple thoughts... 1) the corner being cut off is a really good look and I prefer it better than the 'mouse hole' look of some other designs. 2) immediately after installation, I asked myself why I bought this thing and didn't just cut off the corner (free), but just a day later I had a reason to lock the kitty in the bedroom, so I was happy that I could flip the door down. That being said, there's still a very obvious gap at the cut, so I wouldn't want to leave it down, as it's not a great look, but it serves the purpose of blocking the passage. Overall, 5 stars for shipping, design, functionality, instructions, and quality. I'm very happy I purchased it for the bedroom, but I wish they sold a different type of "cap" that would cover the cut corner for the door that would never need to be blocked.

Great door and customer service

I ordered the wrong hinge and they sent me a postage paid return with the right hinge. The door works flawlessly and the customer service was above and beyond good. thank you

Cats love it.

Got this for me really since I sleep days after overnight shifts and got tired of opening the bedroom door to let them in and out. Fast and easy to install. Only complaint is I ordered right hand and they sent a left hand hinge that was actually stamped with an R for right hand. Used it anyway because I figured we’d keep it open anyway, but if you’re looking to open and close it pay attention to the stamped letter. But we love it, no more getting up for the cats and they no longer wait on us. Win win.

Love these! Great customer service too :)

Love that I am able to close my door now at night and no scratching! The only suggestion for improvement I would have is to potentially trim the corner of the hinge off so it doesn't stick past the door almost into the frame. If you have an angle grinder you can cut it off, but otherwise it sticks out
