In the past I have owned two Praktica cameras and they were great. And on this basis, I purchased the Praktica W20 X 50 binoculars. To say that I was disappointed would be an understatement.
The optical quality was poor and build quality was worse. The focusing ring was stiff and the right eyepiece adjustment was almost impossible to use. Because of the poor optical quality, I cannot be certain but I think that the two sides were misaligned.
I accept that you only get what you pay for but, in this case, I would feel robbed to be given it for free.
