I have had a pair now for a couple of weeks.
they are a roof prism design and weight wise are quite manageble as a hand held binnocular..I find they gather a fair bit more light than my old 10 x 50s...the focuser adjustment is very comfortable and easy to use.
The fov at night is pretty good as far as I can tell and overall they do a good job for a cheapish pair of nockies
While i thought these were primarily made for astronomy use the box is suggestive they are good for terestrial viewing as well..which in my experiance is a bit of a stretch ..while not really noticable at night the outer 10 % of the fov is quite soft .. and on brighter daytime objects they throw up a quite lot of false colour .
Overall they do a good job for the price ..and while they are tolerable for daytime use ..despite what the maker claims ..I don't think they were made for it.
cheers
