Good, so far. Hood dampers almost always are good for about five years. In 50 years owning my 74 Carrera, I've replaced them five times with a different brand every time. Even tried the Weltmeister brand that had a lifetime warranty. Same result and that brand disappeared so no warranty there. Those even ended up making lifting the hood difficult as they fought back instead of pushing up the hood. Time will tell but good, so far!
