Query: fantastic laser pointer

I was hesitant when my son wanted a green laser pointer for Christmas as I had seen several red laser pointers and felt they left one wanting more. I opened his package prior to wrapping and tried it out. Wow. I live in the country and was able to shine this thing across a 200 acre field to an abandoned barn and light up the entire side of the barn. It has so much power; when you shine it into a dark sky the dust particles floating through the beam sparkle and the beam looks as though it is disappearing into space. A fantastic gift for anyone interested in astronomy or who wants a superior laser pointer. There is no comparison to the old red pointers. Caution though, I would be careful giving this thing to a younger kid (<12).
