These are one of those products that once arrived, you'll laugh and say to yourself, "man, this must be pure profit". It looks like something that would cost pennies to make. It's literally just stiff but flexible plastic, very similar to the feel of those stick on wall, wire concealers... with a small piece of foam, similar to the foam used in sandals. Stick on a couple little anti-slip pads and your done. A little initial R&D effort and be paid for continuous years to come. That's not to say it isn't effective. It certainly is! Just wish I had come up with these myself and sold millions of them to people just like me. Got to appreciate their hustle, though. 5 stars. :) I'll update my review if I encounter an issues down the line, otherwise you can assume all is good.

This door guard does the job and doesn't damage your doors. The white foam-padded clasp squeezes the edge of your door so there is no adhesive nor screws nor nails needed. The thick grey bumper is just the right size and firmness to keep a wide enough gap from the door frame and also so the door frame doesn't get dented or damaged with a hard slam. The rotation point works as intended. My only criticism here is that the white plastic clasp is a tiny bit flimsy. A friend who went to use the bathroom (one of the doors we have a bumper on) pried the grey foam pieces away from the door instead of rotating it and the rotation point got bent quite a bit. I think the design could be a tiny bit better if the white part that holds the grey foam was a sturdier plastic and then the end of the white clasp with the black foam on it could be the same flexible thinness so it can still adapt and hold fast to variable door thicknesses. Overall, I took a deep breath when spending the little extra money on these specific door bumpers but I can now sigh in relief that it was money well spent. (Tip: Because these come on and off so easily and fit to most doors, you can bring them with you to your kids playmate's house or vacation to prevent door slamming elsewhere also.)

Great safety guard for our two boys (4 and 2 years old). We have the bought that U-shaped foam guards that can be taken off the door so it will close, those get misplaced. These guards are great, they stop the door from closing all the way, protecting our son's fingers (because they love to slam doors). They can be turned upwards so the door can close fully. We have not had a problem with these. We have bought 2 packages because they are so easy to install/use and are efficient.

Update 2 days later: I've changed to 2 stars, from 5 stars upon receiving the item... the guard already fell off after a day, and is pretty much useless now. The design is a great idea so I am still giving it 2 stars and hope they can improve it, but execution is a miss as the back part is too small - and easily slips off especially if you have a thicker door. I'm disappointed as it was the best design I've come across, but a little too short in the back and won't stay on....

We wanted a door stopper and this works great! It's easy to install, props the door open, and easy to close the door just have to turn the bumper up. However I do wish the plastic part at the back is longer as our door is quite thick and it seems like it won't hold up too well and might slip off...we just got this so will need to wait and see how it holds up. But so far it's a great design and better than other door stoppers out there.

I really like these. We put them at the top of thw bedroom doors to keep them open just enough for the cat to get in/out and still provide privacy.
Three things I really like are the ability to place them in multiple positions to change the door opening, the ease with which they fit snuggly over our tight doors without dinging the door frame, the ability to just twist the foam wedge out of the way. No need to remove it entirely. Big fan.
