The rubber is of good quality, and looks like it should be able to last.
Stick it beside the original door frame rubber and u can't really tell there is an extra layer there...

I really like the 3M sticker, it is very sticky (on a clean surface) and it really make my DIY job much simpler. Unlike other sticker, it will not leave any residue upon removal.

Yet to really test the sound proof but I am already satisfied with the sound of my door closing.
Yes, I have to close the doors harder, but i really like the suction sound when closing. I even open and close a few more times just to listen to it...

As for sound proof, I never pay much attention to it. But, i believe a tighter doors should provide better isolation of sound. How much ? It is really up to individual...

A nice little upgrade which also help u to kill some time during weekend
