difficult to make a lighter product quality the picture is good, really 8x magnification good field of vision the picture is good center and edges but despite all my trials, I can tackle my eyes, always hold me back with binoculars (if hassle lateral stray light) the development is not very close (6m) and it turns annoying (eg impossible to observe flowers on a rock 3m above the head ...) I am tempted to put 4 stars, I put 5 for the excellent value for money (60 euros delivered)
