Product review (5 stars): Do just what they're supposed to
I've had these on for about 4 months.  I think they are great.  They just pop on (no glue).  I've had a few pop off when dishes were too tight against the posts, but have always found the tips and just put them back on.  I have an old RCA dishwasher (in my rental) and the tips fit perfectly and add such a clean look to the old posts.  Recommended!
