i had a pair of plastic levers that crumbled on me. However they were left in the sun for a couple weeks during the summer, right when i picked them up they felt different. I didnt give it much thought, as soon as i applied pressure... bam! pasta noodle (uncooked ofcourse). so that is just another possibility of a plastic lever failing. I guess that is technically user error as i should have put my tools away. lol
