arrived with a broken lock but wasn't about to wait for a replacement

This product was very easy to install. Seems quite sturdy - guess I will know more in a few months. But I definitely recommend it.

I have a Boston Terrier (30lbs, about 11 or 12 inches tall) and this door is perfect. I had ordered a few other brands in the past and the ones they recommended for her size were always small, hard to install, and didn't have much sturdiness to them. This one is the best I've used by far and she actually trusts going in and out with no apprehension.

Assembly isn't hard, but if you use "pet proof" screen on your door, then the clip on feature (to align before using the bolts) doesn't work well because the screen is made to not allow punctures. That was my only issue, but I simply aligned it, used a sharp pointed object to set the bolt hole, put in the bolts, then worked on gently sealing the gate onto the screen. Finished it up by tightening the bolts and it's been super sturdy since the install.

The other item I like is that the bolts you use don't protrude out and snag on anything (other sliding door parts or people), which is nice. The clips to lock the door work fine for my dog as well so the door overall is pretty seamless to the existing slider.

The only item I would consider a concern is the long term durability of the screen that is placed in the footprint cutout in the door. My dog doesn't scratch at it very hard and while she learned to use it there have been only light paw pushes on that middle area, but I can see it bulging a bit here and there. Will keep an eye on that over time as it doesn't look like it's ripping or anything, but I'd expect that to stay a bit more taut since it's the designated push location for the dog.

Overall, great product so far and worth the money!

The dog door was easy to install in the screened door.
Shipping took forever, the order was placed over the weekend, with a delivery date of same 8 days later. The product did not ship until the Thursday, and missed the scheduled delivery by a day.
Just not used to this delay in shipping when ordering from Amazon

Bought this in July to replace a magnetic screen door which always had velcro issues. Very easy to install, about 15 minutes, and took the dog 2 days to get used to it. After about 45 days the swinging screen door got warped and I emailed the company, got a reply the next day that a replacement door would be sent and it arrived in under a week ( this after the 30 day return window BTW ). Don't know how we lived without this over the past years - no bugs - no getting up 20 times a day to let the dog out - perfect addition and great customer service. Highly recomment this product and company.
