changes life of the welder

welder more beginner, well it changed my helmet "life" before, with the mask comes with my position (11 Din) I saw nothing, so I just Soudais next (when we are wrong ... we are bad). Now with that mask I can adjust its intensity and the fact of seeing clearly the approach allows me to be much less ridiculous in my welds.
The mask rocking very well to boot.
I recommend it for novice welders cheap and effective. After time I do not know what it is worth.
