I have the Miller digital elite.
I have used the 150.00 jackson (we have it at work)
and I seem to get a head ache with it. Like it dont darken fast enough.
Never have that issue with my Miller.
Day and night fit and finish is top notch on the miller.
Dont be shy. Big blue all the way.
Good Luck. Speedglass is a respectable Quality Player in the welding helmet arena. I wouldnt be afraid of em. Just have experience using the other and I am more than happy
