The headband is stretchy to be comfortable and can be lengthened/shortened for good fit. The light can be directed straight ahead or lowered through stages towards the ground. There is a hole for recharging through a usb port which can be sealed to prevent rain getting in; or, in my case, landing in puddles. It has one white and two red bulbs which can come on independently or together. You can choose white to come on as main beam, dipped or flashing; red does fast flash, slow flash or on. Main beam is Very bright. The control buttons are easy to use even when being worn. I'm not able to comment on the battery life as I haven't run far with it yet.
Update: I have just done a fiddly diy job in a hard to reach and dark place. This was great for being able to see what I was doing and use both hands. Not what I bought it for but Sooo handy to make a difficult job more easy. I'm now doubly pleased with my purchase and would add another star if I could.
Came in time-slot, well packed for delivery and easy to open. In nice sales box if given as a gift. I'm well pleased with my choice.
