I knew that Livorsi and Autometer were similar but I honestly thought that Autometer made Livorsi/Gaffrig as they're a much bigger company than Livorsi. Either way just because brand X makes brand B doesn't mean a whole lot as a company can spec a product differently. I know some of my Livorsi guages have glass lenses and some have plastic which are already getting the age cracks in them and they're only two years old and only in the sun when I'm using the boat. I've never owned Autometer products but I've heard from a few others on here that they better quality than Livorsi. Thank for the tip to send them in, I'm going to, two year old gauges should not be showing signs of age yet, at least not in my opinion.
