A lot of people I've known that got a G27, have been needing replacements every few months. I on the other hand, got my G25 4 years ago, and it's still kicking, like nothing's happened to it, except for the little plastic ring that hold up the shifter boot fell into the mechanism, making me unable to shift (I had to remove the boot for that to be taken out). The wheel probably needs some cleanup here and there to remove some debris, but it's fine otherwise.
