I have had it roughly 12 years. It has been great. I was able to up grade to a new Zeiss is why I am getting rid of it. This has served me well while I have had it. Lens' are scratch free.
They are one of the best all round useful spotters,mine runs right with a Kowa 554 that was alot of $$.At not much larger size and more field of view.Im going to sell mine just for that reason
