Comments: I had a similar experience with mine. They lasted for one Ragnar and a couple night runs after then died. Replaced the batteries and still no joy. Cheap wiring and overall weak design make this a waste of money.

Comments: Waste of money, don't buy. On my second use, the front lights started flickering on and off, and within a few minutes, permanently off. Turns out the wires are already separating from the LED unit and have nearly broken. Really, really poor quality. I would return, but I've already returned the shoes that the hat came with.
