Every company has it's flaws, some more than others. I personally have never owned anything other than all Swarovski, simply for the reason of their back up service. There isn't much in the way of the top three, Leica, Zeiss and Swarovski but with regards back up service there is only one.
zeiss have tried hard to gain more popularity through advertising there products in the field more with pro hunters but the reality is the people that buy these products off the shelves want the same service as their pro hunters get, and quite rightly too.
Leica have put Simon Barr out there and a few others to try and help them but the truth is Swarovski have never done anything differently......they've just always put the customer first....and called back of course!
