Wonderful piece of equipment. I use it daily for lighting where I'm looking. It's much handier than turning on a lamp and very comfortable on the head. So far, the light it bright enough for my purposes. The up-down flexibility aims the light just where you want when you are looking forward. The only qualm is when I'm looking left or right, I have to slide the headband to the desired direction. I'm not sure if allowing a left to right tilt capability would help, but it might be worth exploring.
