Just bought one tonight.
Got a nice deal on it from the LBS I used to work at about 30 years ago (nice to have old friends). Threw it on the bike for the ride home and it was pre-charged. It's fantastic so far. VERY bright! I can't imagine needing anything brighter than this- I mean dark is dark and this one lit up the road really well in super dark and cast a good noticeable light under street lights and headlights.
Simple charging system, NO WIRES!!!!, lightweight (no pun intended). Basically, it's a light I've been designing in my head for years and finally the technology has caught up to provide what most of us have been dreaming about for years- a light that's compact, easy to recharge, recharges quickly and is extremely bright and solidly manufactured.
