Product review (5 stars): What's not to like?
It's the right part for the right dishwasher.  I hope it doesn't wear out as soon as the original one did -- four years -- but I can't imagine that it won't as long as my co-inhabitants continue to put sharp knives into it sharp-side down. (Which is the recommended method to avoid slashing your wrists, so I can't complain.)

If you need one, buy it.
