Weight? It's surprisingly heavy for its size, compared to other headlights I have had. And it's also slightly bigger. From the first impression, the light itself looks hardy (although the bracket looks a little flimsy, but only time will tell; maybe I'll update this after a few weeks or months of use (if Amazon allows me to). Lastly, the backlight uses 2 flat round batteries instead of USB for charging, so you'll still need to buy batteries somehow.
