Work was kind enough to buy me a new welding hood, as I didnt want to carry my personal one around the world in the off chance that it gets stolen, or broken. I dont weld much but when you need it you needed. However, the new one is so much better that I might accidently leave it at home and accidently bring my personal one along. Bought a Lincoln 3250D with C4 glass technology. and I have to say its worlds above my Speedglass. It has more of a light blue light vs the green. everything is so much clearer, both before and during welding. The only thing I dont like is that you have to have it up slightly to turn it on or adjust, where with the speedglass i could just poke my hand in there. but thats probably true for all pop up hoods the pop up function is also nice.
