When taking a look at the various different types of available wall-mounted door stoppers, I've noticed two main types - ones that are simply mounted to a small hole that had to be drilled, and another similar option - the difference that this second version appears to have a spring inside it. Would there be any particular advantages of mounting a springy type - would the spring in the stopper provide more protection against the stopper itself if a door was hit hard into it?
The difference I have noticed is the spring models are less likely to be pulled from the wall if they are hit by a stray ankle or vacuum cleaner. They will just deflect out of the way and return to the normal position. A disadvantage is some cats find it makes a great toy and will strum the spring for hours.
