I've used these to repair several controllers already. They are great replacements. They feel tighter than the originals but they function just the same.

This stick is a great quality replacement. Install was smooth as butter if you do it properly with the correct materials.
It's a bit stiffer than the original stick box, but that's to be expected.
It's also the proper height for aftermarket plastic thumb sticks. I got my plastic piece from retromodding, and found it was too low on the original box. I got careless and melted my oem plastic piece with my soldering iron. Luckily i had the spare.

The plastic parts are also quite tough to get onto the stick, but it's nothing outrageous. Overall it's a great part in my eyes.
