Quality stuff!

First impression is that they're built like a brick outhouse, which is good because they will be dropped at some point I'm sure. I got them to do some plane spotting as there's a small airport nearby that fly some WW2 planes in the summer. Haven't seen them yet but testing them out on birds has shown the amount of colour and detail you get through these binoculars, pretty good for the money! Very happy!
