I have a big problem with this product and I don't blame you. Has a factory wedding. In the welding position, the entire field of view is covered with what I would call punctiform spots or bubbles. It's clean and this is the first use. I have been welding for a living for over 25 years so I have tried everything to solve this problem including colleagues and CWI. I didn't pay much for it, but it should at least work out of the box. Update: I was hoping the seller would contact me. The lens will be darker, but there is a significant drawback. It's like looking through a glass of pop music. All bubbles. I'm sure it was a defective item and not the seller's fault, but no reply. You'd think they would, at least. I was hoping to get a new one. If you deal with people in our industry, you should know that I'm not trying to rush. I hope to find out who the real seller is.
