As a 10X Zeiss this really is the best quality of all the large loupes. Whenever I get a sample of a new loupe that is meant to be "the best" I compare it with this one, then I sigh and concede that this Zeiss is still the best on the market.
I use this as a 'test' on our exhibition stand - when a customer insists on having the best but can't see the difference between this and a £4.50 loupe - it's time for them to give up and go to see their optician.
A note about the magnification. Zeiss used to quote the magnification as 6.66X with 3.33X = 9.99X combined; then they decided to name it "6.6X with 3.4X" = 10X combined. I think their customers were getting confused with all the numbers, so now they call "3X with 6X = 9X combined. It's all the same loupe!
