Review on 🔦 Waterproof USB Rechargeable Led Headlamp Flashlight, T004 Headlight with 4 Modes and Adjustable Headband - Ideal for Camping, Hiking, Outdoors, Hunting by Shawn Price

The headband seems to be made for a child's head. Uncomfortably tight. Ironically, both flashlights I purchased came with the strap fully extended (as if the strap used on them was an obvious defect/size error). In terms of brightness, this headlamp emits significantly less light at "high" than the optically identical (real) light that I have had for about 5 years. The light output is good yet very bright. The strap is a deal breaker. The two I bought are given to Boy Scouts as the straps are so small. Oh, and 18650 batteries…. They do not pass dyno tests for the stated performance. On average, they all accounted for around 60 to 70% of the advertised 2200 mAh.
