Review on Seattle Sports FireLid LED: Illuminate your Nalgene & CamelBak Wide Mouth Bottles! by Michael Moonin

I saw it on a hike recently, I liked the idea. It fell apart on the trip but was easily put back together. I decided to take a chance as my original lid broke anyway. I like the light, especially great on my glow in the dark Nalgen as it also retains some light. But I found some quality issues. 1. O-ring not seated. I ended up removing mine as the original cap didn't have one and doesn't appear to be leaking. 2. The charging port cover is completely removable - apparently it's designed for a thin mount but doesn't hold up so it just falls out when you open the port.
