Works great! Easy push down and let go, no need to yank the door into it to keep the door open.

This item is sturdy holds the door in place. It’s heavy enough even to hold a heavier, commercial door great item.

Super easy to use and keeps my door open with a 2 year old bent on shutting it! Very sturdy and holds well on my carpet!

Just step on it! Works as it should

This is listed as a "frequently returned item." I had to return one of these myself because the spring inside broke after only a few days, but I bought another one, and with a slight revision, it works fine and has for a while. The issue is that the gripping in the back is too much and you need to assert too much force on the doorstop to get it to move across the floor, which breaks the spring inside. All you have to do is peel off the gripping it comes with on the back (it's very easy, and you can very likely put it back on if you need to) and stick one of those Velcro brand fastening strips (one of the soft, fuzzy strips, not a rough, scratchy one) on the back instead. It will slide across the floor easier and not assert so much pressure on the spring. I'm not sure of this would be suitable for a heavy door on a tile floor, such as in a classroom, but it will definitely work on carpet, hardwood, etc. I'm glad I tried this and it worked, because it's a decent quality, versatile doorstop.

Works great and happy that it is adjustable for floor to door height to work.

Works as designed, but I wanted to use it on my home's front exterior door. The spring of the door stop is so stiff, I'm afraid it might damage the rubber weather seal on the bottom of my door.

This thing is awesome! I need to keep my 70 pound dog out of my cats room. I keep the door cracked with this door stop. Cats can get in, dogs cannot. I’m using it on carpet. Definitely a great investment!
