Rodney-
I've been using a auto-darkening helmet from Harbor Freight for several years. The other day I discovered I left it out in a rain shower face down so it acted like a bowl and had probably a quart of standing water right over the module. I immediately decided it was time for a new one. I disassembled the helmet and started drying it out. The next day I put it in the sun under a clear glass bowl on some heavy screen and it stayed there for three days. In the meantime I went and got another one which did cost about $60. I also bought the extended warranty for three years for an additional $10. If anything goes wrong they will replace it no questions asked. I ended up putting batteries back in the first helmet after three days of drying and it came on and works fine. The new helmet doesn't have an on/off switch, is totally solar, and works better than the older one. I guess that's the result of some improved technology since the first one.
