Review on Easy-Step Door Stops (4 Inch) - Brass (Premium Quality Finish) : Hands-Free by Robb Fillmore

We have interior French doors that remain open. With wedge-shaped doorstops, our Roomba constantly threw them aside and closed the room. I chose to install this product to give us a more permanent solution and they look great indoors too - very good quality of the metal part. They were usually easy to mount with the supplied pre-drilling template. They work well, but the rubber stopper could be a little more rubbery - it's a pretty slick material and they sometimes don't stick to slick floors like you'd expect. The little adjustable knob isn't always adjustable - we have 3 of these and I can't get 2 of them to turn at all. Eventually I'll try WD-40 or something to see if I can get it. The Easy Step feature is secure and requires no tilting to pick up. Overall, they do their job well, look great, and are much preferable to the wedge doorstops we've used in the past. Best of all, roomba can now move freely without being locked in the room!
