Been using my new helmet for a week now. Really like it. the NexGen autodark cartridge has a big viewing area of 4.5"x5.25". It auto-off's at 20 min from last weld, so you are not continually taking it off to turn it back on. Settings are digital read out and easily controlled with gloved hands. 4 independent sensors one in each quadrant. Wich have been working great for tig. Helmet itself is a standard Shadow model. Like how narrow it is but the headgear leaves a little to be desired. No fore and aft adjustment. Bit pricey at $250-$260 list (cyberweld $201.25), but comparable to other brands top models.
I managed to look at another guy's Mille Elite helmet yesterday. Viewing area MIGHT be a little smaller but headgear appeared superior to mine.
