It was a waste of money. It never worked. Glad I checked it before welding. I was supposed to get a replacement that never arrived. Cell led me there. was waiting for a replacement until the claims period was up before I knew it. So I took it apart after finding out I was being taken in for cleaning and found the problem. The solder shorted out the board where the battery is soldered to the board. Yes, it is true. You solder the battery to the circuit board. As soon as the battery runs out, you will see that you are blind. So do yourself a favor. Buy a good helmet or a good interchangeable lens. Don't spend less than 200 if you want to watch.
