Old wedge stop was scuffing my new wooden floor. My entry door is spring loaded and I would need to kick the wedge in to keep it from slipping. This is easy to drop into place over any of the three hinges and the door doesn't slowly slide closed. There's also the convenience of not needing to bend over to install or remove. It also works great on my balcony door where gusts of wind would loosen a wedge.

This seemed like a great product, but I had a few issues with it that made it a poor choice for me. I was using it on my bedroom door since the gap under the door was too high for traditional door stops. The problem is that I get a significant draft through my apartment that tends to blow the door shut, hence why I needed a doorstop to begin with. The problem with this doorstop is that it doesn't keep the door in a fixed position when used hung over the hinges, it just prevents it from shutting. The play it allowed meant the door was still constantly trying to close because of the wind and I quickly discovered the strain was pulling the brackets out of the wood door frame, badly damaging the door frame itself as the screws were stripped out. Needless to say, I stopped using it on any doors in my apartment.

I set it aside, thinking it might be useful in the future under different conditions and thought I'd discovered them when I needed to hold open a self-closing door to a stairwell for some movers. No wind there, so thought it was perfect for that. Until one of the movers didn't see the doorstop and closed the door, snapping it in half. Not quite as indestructible as it seems. I think for the right job, this would be an excellent doorstop, but it does have some limitations, depending on what you need it to do.

Why more people don't have these with them I will never know. It will keep a door open, it will keep a door closed, whether on carpet or on slick hardwood. It can be attached to the top of a security door to keep it open and it is tough as nails. If you are moving a gurney and don't want it to shut on you, or you are worried about having someone sneak up on you from behind; this is the item that will save you.

Works great. Put this under a door and it is staying put!
I like it for extra security where a door will not lock or has a cheap knob lock. Close the door, put this under and no one is getting in without a lot of effort.
Great for hotels too.

This is a great item. I use it to keep the door closed! To keep intruders from getting in. I used to use an alarm, but they are a bit of a hassle. This is pretty solid, you'd have to make a racket and it would take some time to push it out of the way. Enough time to call 911 and get a weapon.
Three sides of it have rubber and it works on carpet and high-gap doors. Just be sure it's jammed in as far as possible.
