Casing seems solid. Hose barbs are quite short - metal hose clamps are mandatory (not included). The bulb on the inside is the actual vital part - don’t know how long that will last. It’s very expensive for what it is though. Installation instructions were good. The warranty is overly exclusionary- it is violated by doing various things that you would do in normal use like touching the quartz sheath or bulb which I thought was a bit cheap. It’s not waterproof - has to be mounted somewhere where it won’t fall in the water
