Reading other reviews on this product made me insane. I bought this, because I needed to open my door, while I'm IN THE HOUSE, to sign for packages, talk to whomever rang the bell, or check for packages on my porch without my miniature dachshund DOGS leading a revolution on my front porch. This product does EXACTLY that. This is not a product that promises to work for cats. It might, but it's not a feline fortress, it's a bow wow barrier. This DOES NOT interfere with my door handle. The very first picture has the Retractable ROLLER anchored to the wall, NOT to the door. The door pulls the barrier out of wall anchored roller. I have a door knob, not a door handle/lever. If your handle looks like anl ~, then change your handle and this product will be fine. Can't imagine returning a $100 product for a $10 fix. Could dogs get under this? No, not if you install it, um, well, as directed. This barrier fills a very specific void, and does just that. How do you enter the house and leave the house with it up? You don't. It's not really meant for that. The product doesn't promise to fill every need...a fills a specific one, for dogs. Not crazy 20ft jumping cats. Why do I need to drill holes in my door? To make it safe, bc the product is literally a dog safety product. If I remove it, there will be holes in my door? Uh yeah, that I can puddy and paint for $5. I'll have to do that for my walls, light fixtures and anything else I screwed into my house. You can't tape this product to the door. If you want to leave and enter the house, with this up? It's not a human access product, it's a dog barrier product. The images for this product are highlight it, not simulate a live event. I love this this item! It might solve problems outside the scope of the intended engineering, but that risk on the person hoping it will solve their issue, that this wasn't made to solve. Rant review over.
