I LOVE this product. We purchased the Duragate with the height and width extension for our large, energetic Rhodesian Ridge-back mix. He is not only incredibly strong but can jump like nobody's business. We installed this gate to separate the front bedrooms from the kitchen and living room and it has worked perfectly! We have been using it for about a month now and have had zero problems with him getting through--not even anything close to a concern! When we leave him in the house he stays in the front half and has been fine. The gate itself is as durable as they say and when screwed to the walls is so strong structurally. The height extender is great and if needed it is easy to add another depending on the size of your dog. It was easy to assemble and install-it took us about 15 minutes.I researched ALOT of different gates and this one is by far the best, and lives up to what they said it would do. I truly think if you purchase this gate you will not be disappointed. This has been a real stress saver for us and one of the best purchases we have made. Money well spent!
