Product review (5 stars): Big improvement in my old dishwasher.
These worked well for almost all of the tines on my dishwasher, many of which were rusty.  Made my otherwise perfectly functional dishwasher much nicer inside and seems newer and more pleasant to load and unload.  They were difficult to get onto the tines - and a few were impossible because they are rusted too much.  I actually got a blister when I started but then switched to wearing leather work gloves and did not develop any more blisters.  I also followed the suggestions of some others and soaked them in hot water (switching out for hot water again as it cooled off and working in batches).  This helped a lot to make them more pliant and stretchy and much easier to install.  None of them have popped or fallen off since installing them a few weeks ago.  I have an older model Kenmore dishwasher from about 2001.  Also, those rusty tines were sharp and I no longer need to worry about scraping my hand with a rusty metal.  I don't know what tool would be needed to cut the rusted tops off to make it easier to install these on the very rusty tines but none of my tools were strong enough to cut them.  Needed 3 more but didn't want to order another whole bag full for 3 tines.
