These are really great door silencers. No terrible noise anymore. No more quarrel with my neighbor because of the single brick wall between us. The operation is soft close like a luxery car. My compliments for the inventer and for the shop!
All good. Easy to install, came with the necessary screws. I had to make some minor adjustments to the cabinet hinges but managed to get the doors to fully close with a satisfying smooth operation. I would recommend you to use some duck tape and experiment the exact location to place them before screwing them in.
