I'm giving this 2 stars because it claims to be for marine use, but clearly it rusts too fast to be for marine use. If it didn't claim to be for marine then I would have given it 4 or 5 stars. Just over a year in the boat and it's rusted to the point that I need to consider replacing it for safety reasons. Look at the pictures and you can see the rust traveling up under the paint. My old one was aluminum and lasted many years, this one is thinly painted steel and has no business being called marine, especially since it could be a life critical device. It's a good thing we inspect it often, this isn't far from losing pressure due to rust.
