Andy, I sent customer service an email about a Big window elite that is about 4 years old but only used maybe 10 times. Always had problems with it so I used my Optrel. Now it said it needed batteries so I replaced them. Is no longer auto darkening. It will shield you once you strike an arc but is black prior to that. Kind of disappointed as it was bought from an online retailer and was not cheap. I just bought some cheater lens as well. Any suggestions
Thanks Rob
