Review on 🔍 Optimized for Online Discovery: Jackson Safety Replacement Cartridge 21947 by Barry Hill

The first lens I bought didn't work at all. I returned it and got a second lens, it worked the first time I tested it. Then after a few months when I started using it, it would go dark for a split second and then turn off. I left it in the light for a few days to see if it needed charging but it still didn't work. That was a lot of money for something made in China, I wouldn't mind if it worked.
