This is my second Taz light by far my favorite. I purchased it for my hour commutes because I can run the light on low and have enough juice for 2 round trips (just in case I forget to charge it). It pivots easily so I don't blind oncoming cyclists and pedestrians, and in really bad weather the high setting provides a fantastic amount of light to make it home safely. Love the ability to cycle between high and low quickly, also works great mountain biking. The battery life seems to be a little shorter than advertised, but I probably haven't run enough cycles through it for a fair test.
