"The options are set, the glasses very easy to handle", "The three nosepiece are easily replaceable"
-> Definitely not. The replacement of the nosepiece is incredibly difficult. The first replacement was with difficulty yet, by switching back I gave up after a quarter of an hour and cut the connections with scissors.
"Do not fog up when you follow the handling guidelines of the manufacturer."
-> There are at no "Handling Guidelines" / directions for use!
No recommendation from me.
