I think I say a lot that I love substantial things, things made of real metal, solid and made to last. This is one of those things. It's pretty simple as a door stop goes. It is exactly two inches tall and one inch diameter, so it is EXACTLY what I expected. And it weighs a half pound! The top screws off and a screw can be inserted through the bottom. So no mystery there! and it comes protected in a foam wrap of some sort with the single screw in a baggie. I hope the reviewer who wants to "repaint" his stop "rethinks", as this is a $25 piece of brass that should NEVER be painted! (That was a suspect review, if you ask me!)I usually take price vs quality into account to determine value. This thing is possibly overpriced, but it's hard to say with solid brass--so many things boast to be solid and aren't, so I've forgotten what such things cost. Nevertheless, it is such a lovely bit of floor bling--and I'll be the only one who knows how good it is as nobody will take a second look when they bang the door against it. So it gets five stars despite it being a tad pricey. Our entryway has a coat and hat hanger behind the door and this is going there to protect the wooden wall rack. I expect zero problems, as this couldn't be simpler, but as always, if something goes wrong, I'll let you know. This can be screwed into wood or you could use the wall anchor into the floor. A hole can be drilled into concrete for the anchor and the screw can be inserted into that. I have a tile floor, so I'll drill a very shallow hole and squirt epoxy into it and press the stop onto the epoxy so some enters into the bottom of the stopper. It won't go anywhere. [UPDATE] I did something really stupid that you might enjoy. I can't resist challenging products to see how and when they will fail. This stop is anchored to our tile-over-concrete floor at the entryway, so we have a steel (hollow) exterior door that gets knocked against it. I wanted to know how much abuse it will take but did't want to risk hitting it with a hammer. So, I flung--and by flung, I mean really flung--my door against it. Stopper 1, door 0. Should've used the hammer. I am now the proud owner of a significant dent in my door. The good news is that the door needs to be painted anyway and a little bondo in the dent will make it perfect! BTW, I drilled a half inch diameter hole about an inch deep into the floor and pressed J-B Weld epoxy putty into the hole and into the stop so that it oozed through the bottom. I then pressed the stop onto the putty and inserted the screw that came with the stop down into the stop and into the floor (rebar). It Ain't Goin' Anywhere!
