Great product, and fast shipping. Could not be happier with it. My first auto-darkening helmet, and I am extremely impressed. I did a lot of research and decided on this one because of the new filter technology. It far surpassed all of my expectations! Completely blown away by the visibility of the weld area! I am just nervous to put it through too hard of use, because I don't want it to get damaged. Not that I am worried about it's durability, as it seems very well built, but I am very careful to avoid any overhead welding since a replacement lens would be so expensive. I was a little worried about the side windows being distracting, or annoying if another welder is around, but haven't had any issues so far, plus it does come with covers for the side windows if you choose to cover them. However I think it would have been a better design to have them attach to the outside of the helmet, rather than the inside, to ensure that the side windows stay protected.
ProsIncredible visibility, simple controls, comfortable headgear, reliable darkening response, and quality product
ConsKind of expensive, but still worth it. A little bulkier than some other models you might find, which might make it harder to work in tighter spaces, but not much a problem for me.
