Review: Awesome. - This light is great. Long battery life, nice and bright, multiple light colors and very durable. A bit heavy, but that’s fine considering how nice it is. Haven’t really gotten it around water much yet, but so far it’s held up to some light spray/drips and a pretty damp environment at work sometimes, so I’m giving it 5 stars. If it fails, I’ll update this review.
Review: leash string broke - mostly solid flashlight. my only complaint so far is that the leash/wrist string it comes with broke within the first week. it's a pretty thin piece of string that goes through a small hole in the end. i guess the hole has some sharp edges? cut right through the string with just a few pounds of force. and the hole is pretty small, i doubt i could get a beefier string through there. otherwise, it seems like a solid flashlight so far.
