Before my tip broke off it showed no signs of weakness. I did, however, take it out for a while and left the short ESC dipstick in. Then when I went to check the stock dipstick that's when the tip broke off inside. Maybe keeping the stock dipstick in the engine helps and taking it out for any extended duration hurts? All I know is I'm not ever putting that plastic bit back in. ESC says "Your estimated delivery date is: October 29 - 31" and while this has taken so long I've bought a house in the interim, I'm holding out for their dipstick.
