What is the best door stopper?

Door stoppers vary in their construction, design and materials. These need to be heavy enough to stop the door but must not be too large. Thus, you will need a door stopper that is obscured, large but does not catch a lot of floor space. A perfect material on this case is to use concrete but the same can damage your expensive door. Thus, the best door stopper is the one that can achieve the desired results, stop the door and eliminate any form of damage to the adjoining wall.
