Husband said the lights worked well when checking off paperwork outdoors, as he drives a truck. Also came in handy when he dropped something in the cab where the overhead wasn't strong enough. My son was checking it out as well. Only drawback was that the buttons behind the cap he had to keep fishing for. I think after wearing it a while, it would have become easier to locate readily. It was purchased at the tail end of winter/early spring; so only used a few times in the evening. Price was reasonable, so if I see it again, I may buy it for my son anyway who also works outdoors. Will probably save as a Christmas gift. Can only benefit anyone who works evenings, outside, in a garage, etc., and needs to keep both hands free.
