Worked perfectly. Click is a bit softer than an original. But works perfectly as a replacement. Texture of the surface is good. Not as smooth and glass like as the original. But still has a very good feel. Not plastic feeling. Feels like a finely sand blasted metal. Didnt have to reset smc or anything to get it working either. Shut down. Install. Make sure you don't tighten the larger disc screw too far since that's where it clicks. Adjust it to how far you like the click. Make sure it's plugged and and close the MacBook up and you are done.
