Has anyone used the BlissLights? I keep seeing pictures and think they look really interesting, but I just worry that they won't look as good in reality. They retail at over $100 each but you can usually find them under $60.00 (refurbished) at Amazon or Yugster. The fact that you can find them refurbished so readily makes me think there are a lot of returns. If they live up to the pictures, I think they could add an interesting dimension.
