Question: Are these hard or squishy?  Flat or round on top?
Document: This heavy duty round bumper is not good for anything that is for flat surface. This bumper makes things much more slippery than before,  Those that have read in previous review were correct when this item was used to protect flat glass table top. this item becomes more dangerous for used in this manner. I recommend flat surface bumpers instead.
I used these hard rubber bumpers to replace the worn-out squishy pads on my kitchen cabinetry.They work okay, but not perfectly. Cabinets now "bounce" closed (the door hits and then bounces a little 2-4 times).
Well I don't know what you all are going to use them for but here's what I did and what I can say about them:I'm an electrical engineer and had some left over round circuit cards that I wanted to use as coasters. I have glass tables so I can't put anything on them that will scratch glass.3 of these per circuit card makes a great coaster! Here are some features:1) Strong stiction.
Inexpensive, unobtrusive and very sticky. I was able to move one and it still stuck well. Kind of hard but serves the purpose.
These bumpers are too hard. I was trying to find something that was comparable to my silicone bumpers and these just made the thud louder when I close my cabinets.
The bumpers slid off. At least when attached to certain hard materials. I mean, it was ineffective for me and I wish I could get a refund.
I bought these to cushion the cabinet door closings. Unfortunately, the bumpers are so hard that it made absolutely no difference in the sound when cabinets are shut.Probably would work as picture bumpers.
These are rock-hard. Probably good for putting on the bottom of things that you don't want to slip around on a coffee table or something like that, but definately not for the inside of cabinet doors. Can't really knock them for not doing what they were not designed for, however.
This is a great idea, and I bought to insulate the drawers and cabinet doors I have in my kitchen. The nubs are rather deep, so the drawers don't close fully with these on. The material is also too hard and is LOUDER than closing my cabinets without any protection at all. Go for the foam kind, if you can.
They did not stay where I placed them. My glass top slid off them. I am looking for another solution now.
Answer: yes
