For some time I am looking for a doorstop that prevents the door handle of the door to a - suggests cabinet - standing behind the door. Conventional stoppers which are positioned at the bottom or firmly bolted to the door, came out of the question for me. Such things seem oversized and also look ugly (clunky) from. By chance, I found a smart solution for this problem at Amazon. Although the reviews are very mixed on the doorstop, I've ordered a set (3 pcs) of rubber buffers. This decision was - now in hindsight - correctly. For mounting on the door handle, the inner bore of the buffer should be brushed with Vaseline and then slipped on the door handle. After that the buffer is slowly pushed to the end of the straight cylinder handlebar. It is best to press alternately left and right of the hole on the rubber edge surfaces. This one pushes the door stopper (piece by piece) slowly forward. In my case, the stoppers have been mounted on a door handle having a diameter of 20 mm. The inner diameter of the doorstop (14 mm) was so dilated to 6 mm subsequently. The material is resilient enough to cope with the expansion harmless. In the end position of the buffer is then seated firmly in place. Now just remove the Vaseline of the handle bar and the protection is mounted. For me a fast, easy solution that wall and furniture surfaces from damage by impacting doorknobs prevented. Therefore 5 stars
