Ok not great - Pulsar Axion Key XM30 2.5-10x24mm Thermal Imaging Monocular

Aside from having a quick guide there were no instructions, so its up to you to figure out what the symbols mean or do. It does not work/locate in prairie grass or timber/brushy areas, and forget about it working through your vehicles glass. The battery charge port is hard to hook up and no meter as to battery strength. I still have no idea what some of the icons do or what/default settings are or how the second screen is supposed to work due to no owners manual. Go for the mid price range units, I wish I would have.
