I have a Minewt x2 for commuting. I like it a lot. It's small, bright and easy to mount. Right now I only have to use it in the evening, so I only have to charge it once every couple of weeks. It's bright enough to see by even when there's no street lights, but no, I wouldn't go charging around with abandon. I tend to slow down quite a bit. In general, unless it is complete darkness I use it on its low setting.
