Yes dear, your christmas present is fantastic.Wait a minute...who paid for the lights?
The Arc is awesome though. We have the NiMH batteries. I've tried the NiteRider and it was bulky and awkward on my head. The light was also a little too white (or perhaps it was just the light's placement on my head), but it was difficult to see depth. I don't have as much of that problem with the Arc. I also liked the Lume I tried, but their model with a quick charger is on severe back order. A little more expensive than I ended up getting the Arc for too.
