[MENTION=465722]robertorolfo[/MENTION], this dynamo is inside the hub of my front wheel, so I'm not rubbing a bottle-shaped dynamo against the sidewall of my tire. No adjustments needed. The lights are bolted on, and wires run from the dynamo hub to them. It's more reliable than anything by far.
I supplement these two lights with a battery-powered flashing tail light and a battery-powered spoke light. I charge the tail light with USB every month or so. I replace the button cells in the spoke light every two months.
