I have two of the 1 aa polymer body Defiant flashlights from Home Depot. They look identical. They were purchased as loaner, don't care if lost lights. Purchase price was about 8 to 9 bucks. I became aware of them from a post here in Budget Light's several years ago. The older one has a flood beam and hour and a half runtime. The newer one has a throwy beam and three hour runtime.
They have been dropped, stepped on, muddy, greasy, dug out of snow, covered in brake dust. Several times I thought "they won't survive this I will just get another one". Washed in the kitchen sink they look almost new. I have loaned them to plumbers, hvac repairmen and neighbors. They have become my go to trouble light when something needs attention. They are not fancy, no multiple modes, no great tint or super long runtime. They just work. Never had that kind of luck with a Maglite (2aa Incandescent). In years past I went through several. None survived. I have not tried any of the current led versions. My 2 D Mag seemed tougher but it walked off.
Let me just say, these lights could fall apart any minute. I had my doubts about the durability of the switch boot and the plastic lens from day one. There's that rule though... Sometimes you're wrong.
