Product review (3 stars): Caution if you don't use extra bearing too.
While the instructions were better than most, it would be nice if they included a cautionary statement applicable if you choose to not use the bearing seating tool.  While it warns you that part of the bearing will still be exposed, they should warn you the bottom bearing is not and should not be fully seated into the race or it will bind and not allow the basket to spin freely.  Check that it spins freely before and after you put the bottom nut on as it can also cause it to bind.  I believe the tool prevents you from pressing it to far into the race.  I successfully installed without the tool and it works great.
