I have not found the solar
vents from Nicro to hold up that well. I currently have two that need to be replaced. I do not feel that they are worth the two hundred dollars for the few years of functional service
; ours get a lot of salt
spray. I have found that Beckson Marine
makes a non-solar vent that will fit my 4 in hole and only fifty something dollars each; one hundred plus dollars verses four hundred. OK I'm cheap!
Has anyone used the Beckson vents? For fifty dollars was the quality ok?
I know that the batteries can be replaced on the Nicro vents, but it is more than that wrong w/ them. They do not work at all and have moisture between the layers of the solar panels
