Paultricounty: the Ultravid 7x42 had focusing issues, the focuser seized up a bit near the far end which was annoying. The dealership sent it to Leica for servicing and it came back a few weeks later with a sticker that said "it has been serviced by ______" and a note. Nice, but the problem was still there. The dealer agreed and said there was no point in sending it back again and since Leica was in the midst of rearranging their sales organisation (his words) he could not say when he was able to get a new pair in. It is a pity, I loved the optics and the overall handling. I found the NL easier to snap into focus than the Ultravid 7x42 but I certainly had zero complaints as to the optical properties of the Leica. The focuser on my sample was definitely subpar for the class though.
I honestly feel that the person servicing the optics sat by a desk and just turned the focuser a few times after lubricating and thought "well, this is within specs for sure" but if the person had actually peered through the binos and focused at something outside the window about fifty meters away there is no way they would not have noticed the focuser binding, going from smooth to coarse and then smooth again.
