I go back for the 6 month checkup next week. It snaps, crackles and pops sorta like before it was replaced but it doesn't hurt as much. And it's stiff especially in the morning. The range of motion isn't what my left one is and they say it never will be. I guess it's not like replacing a bad piston ring or changing oil & a filter. I'll be happy with it if I can get some life out of it. I hope yours holds up.
