Fast shipping but 9 times out of 10 while welding it will shut off like grind mode on other hoods. The lens flickers then sometimes will kick off all together. At first I thought it was the way I was positioned but it did it almost 5 times in 1 day. Other guys used my hood and had the same experience. Tried to recharge the solar but its been doing it since day 1. Very disappointed in miller.
