Product review (5 stars): Don't be intimidated but know what you're getting into.
The bearings in our washer were beyond shot.  We were unable to finish the spin cycle without getting unbalanced load errors.  This kit solved the problem.  I like to think that I'm handy.  I'm not, but that's what I like to think, so it took me a long time to replace the bearings -- budget about 50% more time than you think you'll need.  Other tips: wear gloves -- taking the rotor and stator off your washer are knuckle scraping activities.  The instructions don't tell you you need to remove the inner tub.  You do and there are some good YouTube videos that teach you how to do this with a 22" piece of 2x4 and a car jack.  That works like a charm.  Finally, be absolutely sure that you don't leave the stator wires in contact with the rotor or it will wear through the insulation and cause a short.
