CoJo Premium Rubber Beige Door Stopper 3 Pack – All Floor Surfaces Door Stop – Home and Office Flexible Door Stops Non Scratching Strong Grip - Wedge Doorstop Non-Skid Rubber Base Grip –5 Bonus eBooks

Very convenient and flexible enough to get under the door tightly. I like the hook so that you can hang it on the door knob when not using it, so it does not get lost or misplaced. I don't really like the color, though, but it is not a biggie.

They work really well on carpet and linoleum. The dogs really like the texture of these, have already lost 2 as "chew toys", thankful for the hook, the last one is out of reach.

They don't hold classroom door unless in just the right place.

I love these! The fact that they can hang on the door when not in use is tremendous. We do however, have one door with a large gap, that these did not work for. I'll get something specific for that though.

Wish the color was a little more neutral/ivory but these are great to hang so they're always there when you are looking for it. Use them to keep the Roomba sweeper from closing the doors.

It is clever that they can hang on the doorknob when not being used

Too light can't grip and hold the door on my wood floor.

Too small for some doors, but product quality is good.
