I really liked the concept, however, there is no way to dim the light. It is either on or off. Another thing, the protective plastic on the lens that covered both sides left a cloudiness. It could still be used and words could be seen, it just was a little annoying, cleaning with lens cleaner did not take it away. The plastic had really adhered to the surfaces, it peeled away but left the cloudiness. I also needed to tape the door to the battery compartment as the slightest touch on the door caused it to open. Again, just annoying. I hope my friend can look past the annoyances and find it use full.
