The light is very bright and works every time he turns it on. The band does not slip at all. It stays put. In the couple weeks he's been using this headlamp the band has not slipped or stretched at all. We have another one that doesn't stay put this well. The band is always readjusting on it's own. This one does not do this which is really nice.
You can get this Amazon here. It's a good price for how well it works.
All in all this is a good item for the price. It is sturdy and works well every time. We will definitely be purchasing from this company again because the quality of the product and the price of the product appear great.
Have a great day!
