I bought two sets (1 for my router table and 1 for the table saw) 11 years ago (2013),,, The router table seem OK (used occasionally), however, the tablesaw (hardly used) set are not mush... yet... however, I can see pressure indentation and can sink a fingernail into the tyre, The dedicated tablesaw bought in 2014 seem ok, though I use them a lot.
Would be interested in any replacement details.
If your first cut is too short... Take the second cut from the longer end... LBD
