I was hesitant at first due to cheap price had to be junk. Then I figured a $14 experiment was worth it. It was. Seems solid enough out of the box. Solid mounting hardware.
I got it mounted, and it was very bright. Next test is of durability during hunting season in the mountains and streams.
My one regret is not buying the switch kit (obviously my fault, not theirs). Although mine works, it was cobbled together.
