This small headlamp is everywhere online, in my opinion, it's a cheap headlamp worth for trying. The built-in battery(may not good one, but think about the price) can not be replaced easily, but if you can replace with a premium 18650 battery as some sofirn fans did, it becomes a long-lasting mini headlamp with magnet. --- Barry
