Hi, I have purchased despite some bad Rezesionen which NightSpy. I think for around 100 euros this night vision device is absolutely properly adjusted. We thus observe our hedgehog in the garden and other animals such as mice that feast on our bird feeding station. The environment is very good to see and the IR lighting makes everything up very brightly. The device I would recommend to anyone who does not want to spend a lot, because he does not need it professionally.
