Here, since they are, in effect, half the size of a regular pair of field glasses, better quality optics can be afforded, as the cost will be proportionally lower. The need for using sophisticated equipment for viewing the stars has limited the number of participants.
Modern binoculars come with a variety of coatings to protect the lenses and improve the brightness of the observed image. Hunting binoculars should feature some sort of rubberized exterior armoring to protect them from being damaged if dropped or bumped against trees, brush, rocks and so on. With a cheap telescope, this will be of no use to you, as it will be hard to keep up.
As with the aperture of a camera lens, the size of objective lens determines the amount of light that can enter your binoculars. More magnification always means less field-of-view. The size of the binocular will probably affect the way they feel in your hands.
The only negative review I have to offer that the lens caps are cheap and are nowhere near the quality of the rest of the binoculars. If you are going on a long trip, binoculars will be excellent entertainment for kids.
