I found out that the Metal ones, the cores like to corrode and i broke 3 of them trying to Remove the cores. At least with the rubber ones, its easy to replace the stem portion making cheaper the replacing the whole thing. the worst ones are the Ford TPms sensors. They use a band type mounted towards the middle of the rim and they are easily Broken when Dismounting a tire if your not careful.
