I have used the MiNewt through this winter for commuting on side streets that are completely dark. It is bright and reliable even in the rain.

Here are a few things I learned from using it:

• The light charges from a USB port. I can easily ride with it in the morning, charge it while at work, and use it for the return trip.
  
• I keep it on the bicycle during the day with a flashing mode so cars can see me better.
  
• I keep next to it a PDW 1W LED Cosmic Dreadnought 110 Headlight. This is for redundancy. I also use it in flashing mode at night next to the steady light from the MiNewt.
  
• The battery life of brightest light is 1.5 hours, before it starts dimming.
