Yes, I've made a little worried, because with security technology trade-offs are always a bit tricky. But compromises you go always. I plan to only very rarely to weld and then no extensive things about this product and there was plenty of Amazon reviews, I think this. I have that always unpleasant pushes a big head and a face shield. This welding helmet can easily be put to my head. Even my glasses does not bother. The weight is not a problem. Yesterday for the first time so welded - yes, it works perfectly. No matter how many milliseconds the now, of bright light of a welding arc I missed at 90 amp manual welding. Was there somewhere criticism of plastic instead of glass? If this thing gets annoying scratches or branding a slag, I wonder if I the same or a more expensive buy. For the price, I do not upset the. Annoying I found that bright light from above falling behind just on a bright yellow sticker in my field of vision. Does it have to be that way? Unfortunately I have no comparison with other helmets. The manual is expected to be a bad joke and that gives a star deduction. I would like to know how long I can trust this machine if I have to put it in between in the sun to recharge batteries or whether even after long inactivity time accumulates enough power in the dark. Because in it the battery will eventually be old?
Without good manual I'll probably "safe side" to adopt in a few years of the helmet - so there is no five star.
