2006 roundup #41: GuyotDesign's Gription, Firefly and water bottles

The Firefly by GuyotDesigns was blogged far and wide.  Its gimmick: replace your water bottle top with a Firefly and you can turn it into a glowing blue nightlight.  This product illustrated two things: sometimes green gadgets get picked up simply because they've got the tech equivalent of big baby seal eyes (even if the actual implementation isn't very good: the Firefly fits few of the water bottles I've encountered, installing it is a pain in the ass involving a specialized wrench you're sure to lose, and replacing the batteries is even more annoying) at the expense of better products that are deceptively simple (the Guyot Gription anti-splash lid is fantastic and far more deserving of widespread attention, as is their steel water mug).  [GT]
