Its not as bright as the $20 ones. It's not as solid as a $20 light. And i feel as if it wouldn't take as much abuse as a $20 light.
That said, they are also 1/3ish the price.
Given the design, they certainly don't seem to be water resistant, but i didnt see any claims that they are.
If you want a simple headlamp for around the house, they do the trick. Buying these for workers? Certainly appropriate for workers who don't take good care of their equipment.
The problem is....
They aren't lasting. The switches on them are failing. See the video? This a brand new one. Never worn. Sat on my shelf for a two weeks. About to assign it to a worker... And its not working.
