I took a gamble on buying one of these helmets, I'd done my homework, read a few reviews on various top of the range helmets, and then made the decision to buy the crystal 2.0. Their slogan is...."you won't believe your eyes" Well, I can tell you, that slogan fits this product like a glove, I was amazed to how good these are, unbelievably good. Expensive yes, but you get what you pay for, and these are worth every penny. I'm no youngster and my eyesight isn't what it was, but using this helmet has improved my welding vision to a much higher level, the clarity of the weld is astonishing. If you're undecided in whether to buy this helmet or not?! Don't be, you'll not regret it. On a side note, the service from Inverter Fusion was first class, from the moment I made an enquiry to the quick delivery was first class, highly recommended, thank you Craig.
