Customer feedback

Comments: Bright and blinding light. As a light its great, but I had trouble positioning it just right on my head that would thrown light on the ground in front of my and not on the general front of me. But when I do get the right position, very comfortable to use and not too heavy.
From: Smitha, Atlanta, GA

Comments:  Great potential, but cheaply made. The illumination is great and it feels practically weightless, but this light only lasted for 4 months. The plastic clasp holding the batteries is very thin and snapped during a run.
From: Andy, USA
