So, I bought this because it made sense to me. Finally, an affordable utilitarian light that doesn't require batteries and is solar charged. If you are looking for headlamp performance this is not the piece for you. The light isn't focused and isn't adjustable but for its size puts off quite a bit of light. The key is that you never have to replace dead batteries and never have to be in that situation where your batteries are dying. Overall, I use this thing all the time because of this simple detail...
