I bought this light from some seller on Amazon a month or two ago and it has really come in handy for the nighttime dog walks. I think maybe my only complaint would be that the "mid" range output is a little bit more than I was expecting, and the "high" and "turbo" settings are only barely noticeably different. I end up using the little auxiliary white LED for mid settings and rarely use the main LED for anything above mid ("high" has come in handy a couple of times, it just isn't necessary most of the time).
The thing is, what that tells me is that there are one or two settings under mid that might have been useful in the house if they had existed. The low setting is perfect for not blinding you at night if you want to read something (not that I have run into a need for that, yet, but I've tried it out), but it is a little too low for navigating kid toys in a dark home. One setting midway between low and mid would have made this the perfect headlamp for me, but that's not to say I don't like it. It is a great little light.
The headbands are comfortable. I took off the top strap and generally use it strapped around a hat. I can't tell you whether it would be good for running/jogging/jumping out in front of moving vehicles, but it seems like it would stay on my head if I ever decided to take up playing jaywalk-chicken at night.
