Familiarity: I've used it several times
For the price it works great and does exactly what I wanted. It is bright enough to be seen well in the daytime and it stays right where I put it. I ride in Wisconsin on some rough country roads beat up by winter and this light stays put. It doesn't drop down or rotate. It is in the same place at the end of my ride as it was when I started.
