Definitely quieter and smoother. The cracking and snapping noise is gone. The door is much smooth also, the door did not like to open from partially open, now no problem. The old rollers were fairly worn out and sloppy, these new rollers are very smooth rolling and quiet. The metal thickness is thicker and stronger than the original hinges. Fairly easy project took about an hour to do the hinges and rollers. I did add roller sleeves (10) from ebay, I think this helped also.
I would recommend to anyone with a bit of know how to do this, take it easy one hinge at a time, cordless impact on low setting helped.
Two thumbs up.
