If they are anything like the old ED ' Epic ' line they will be a nice eyepiece all round , probably with way better coatings tho .
Like comparing my long sold 102mm Celestron from the mid 90's to the new Saxon 102 I have now , a much brighter and sharper image probably due most to the coatings , but also the Chinese have also come a long
way in optic figuring and polishing since those bad old days .

edit , On reading Nicks reply I would believe that just on the image my 102mm Saxon ( Chinese Vixen spec ? ) gives , after a bit of colimation its very , very good
