Review on BenRich Rechargeable Waterproof Mountain Headlight by Leo Black

All-Metal Construction. The bike racks are strong and stable. Quick release brackets for removing from the bike when you want to secure it. Took a late bike ride to a bar and grill about 10 miles away. There was a lot of daylight on the way there, but by the time I got there my phone was running low. I was able to use this flashlight's USB port to charge my phone while I ate. There was still enough power left to light the way on the way home. Highly recommended. The only downside is that I still don't see the need to take it apart should I want to replace the 18650 lithium cells in the future when they no longer hold a charge.
