Review on Room Starters' 20-Pack White Silicone Rubber Door Stop Bumper Tips: Universal Fit Replacement Stopper Ends by Leo Torres

I have these spring-loaded doorstops all over my house. They measure just over 1/4 inch wide at the top of the end. These tips are good. Silicone should provide soft rebound for a long time. They fit well and seem to stay in place. They're slightly wider than the original tips, which were more plastic, and have nicer rebound. I think the Roomba handled the old ones pretty well, so I'll mention it in case these new ones suffer the same fate. .Lowes had a pack of replacement tips but I didn't realize that the pack of 8 tips has 4 designs so I only have 2 useful tips in the pack. They were cheap and made of hard plastic, I like these silicone ones better. It's weird being happy, but I like these doorstops.
