Another cheap tool from HFT that works. If you have never had an auto darkening helmet, they are a treat to own. Sensitivity , amount of shading, and time duration to see through the filter after welding are all adjustable. I did own a really good one before that some thief made off with, so I know a little about them.
The good is of course the price and that the controls work. It is also very light in weight and that makes the thing more comfortable.
The bad is that it is paper thin, but that is not a durability issue because the thing is very flexible and not likely to crack. The unit is powered by the act of welding and the solar batteries do most of the work. However, it also relies on two coin cell batteries permanently soldered in that cannot be recharged, so in essence a throw away unit when those are depleted. "Expected' life of the batteries is five years, but who knows?
People have hacked repairs on them to make the batteries replaceable and that info is out there somewhere. I also like a nice clear shield, so I tape a sandwich bag over the plastic spatter shield and can see thru it in a perfect manner. Change it out every use and it stays like new

I rate this one a BUY for the occasional user like me.
