I bought two of these headlamps for friends who were going cave exploring. I have one myself, and it works okay. The light has a medium brightness and could be better, but it's okay for the price range. It fits comfortably and can adjust to fit pretty much anyone, no matter how big or small your head is. It also comes with 2 AA batteries that are nice to have especially since the batteries run out pretty quickly. The light bulb is not a LED so it is yellow light, but it runs out much faster than a LED would and uses more battery. It is built out of rather durable plastic but hey, plastic is plastic! These are not heavy-duty touch kind of headlamps; they are more meant for light usage.
Overall these headlamps work well but not amazingly. Don't expect too much from them.
