Customer Reviews for VEVOR Dog Door for Sliding Glass Door, 1927 - 2049 mm Adjustable Height Doggy Door for Sliding Doors, Aluminum Frame Tempered Glass Pet Door with Hinge Structure Flap and Lock for Large-Sized Dogs

The shipping of this item came quickly, and packaged in a decent sized box easy to bring inside. The instructions were easy to follow and assembly was easy. Once the dog door was in place and assembled, it was easy to use. A very good buy and purposeful item. I will say that I installed some insulation around the inside and outside of the door to keep out bugs as this dog door was not as thick as the patio door. Also there is nothing for the patio door to latch in to the dog door to keep it closed over night. Still a great purchase and a good price for the item.

Fabulous, heavy duty dog door. We bought this because it had a low entry, 3 inches or so for an elderly chihuahua. It also accommodates our golden.

I bought the large one which is too big for my dog but it is the best purchase I ever made. Not having to worry about letting the dog out was great.

Such a good find! the door arrived quickly and is sturdy and well made. Installation was about as easy as your standard IKEA Flatpack and all tools were provided! So happy with this purchase

This pet door was much cheaper and way better than the one I bought at home Depot that needed to be replaced after only a year.

The vevor dog door works great for our 85# dog.and our cats use it also.Easy to assemble and install. Would highly recommend.

Wonderful Product. Easy to setup. And a great price. Seems to be good quality too. Lots of glass and thick aluminum. Couldn't have asked for anything better for a big dog!

Great quality and fits fine. The instructions were a little complicated to follow, but just using common sense allow for a smooth installation.

I searched for ages to find a dog door that had a flap big enough for all my dogs, wide bulldogs and French mastiff. This was the largest I could find that was under $1000. It’s easy to install, it’s very sturdy and durable and $300. It was so cheap I thought it must be really poor quality but I was wrong. I’ve ordered a second one as a spare.

Wasn't sure what to expect, but very well made. Not cheap materials at all and fits great. Easy instructions and all 3 pets learned first try. Highly recomment.
