Review on Enhanced SEO: Instapark ADF Series GX-500S Solar Powered Auto Darkening Welding Helmet - Adjustable Shade Range #9 to #13 (American Eagle) by Alex Webster

Bought for my husband in June. He used it for the first time and injured his eye. He thought he might have accidentally stumbled across the dial. He used it again this weekend and burned his eyes badly. He turned the knob to maximum and it didn't work. Now his eyes are bloodshot, he can still see the haloes a day later, and his eyes hurt. I highly recommend this helmet!
