I looked at my computer, made money and was about to die when the package arrived! I pulled this thing out, put it on my eye and felt like a kid again! All day we gazed into this Christiline wonderland of light and colour. All the kids reacted like this: "Wow! Wow! Wow! It looks so cool!โ After much experimentation, I decided that an attached headlamp was the best light source. It's just brighter, more vibrant and easier to work with.
