Overall, this unit was exactly what I was looking for. This unit reminded me of the Military night vision devices that I used before. Functionality and ease of use. Turn it on, and adjust the focus and your ready to spot. The built in Infrared has a tremendous distance. Only one draw back that I could tell. The focusing could be a little better, but still the unit would get a score of "A" from me. Very pleased with the product and the price.
Pros: Functionality, portability, ease of use
Cons: focusing could be a little better
