Product review (5 stars): Great repair for an old dishwasher!
Love these!  My old dishwasher still works great but the racks were beginning to show signs of wear on the tips of the tines.  Thought I would do a little preemptive repair before they became worse.  I already had a tube of aquarium grade silicone so I used just a tiny bit on each tine and pushed on these covers.  It's been several weeks now - with lots of use and I've had no problems at all.  I read where others have had problems with them coming off so I check after every wash to be sure and none have come off so far.  Even seem to hold my dishes in place better.  Couldn't be more pleased.
