These are just awesome headlamps with motion activation on and off function. Very bright led for lighting up you work area o completely hands free and rechargeable with included charging cable. A very comfortable elastic head band keeps it in place on your head so no more looking for a flashlight after laying it down. How agrivating is it when you are working on a car or something and you sit down only to realize you layed down you flashlight in another spot so now you have to get up to retrieve it?!! Frustrating as heck in my opinion. These being rechargeable also is great for saving money on batteries and better on the environment. Be prepared for your next project or just preparation for a flat tire. Also great for early morning joggers and anytime hiking or power outages. Just a great all around. I'm glad I bought them and am sure you will like them too.
