I have one of these scopes myself and I love them and in my opinion you have to spend a small fortune to beat the colour correction and on axis performance of these scopes. Strange thing is mine as well as every other one I have ever seen suffers from sticky paint syndrome to some degree or another.
average as it has very sticky paint this happens to almost all Kowa scopes of this era with Kowa that actually get used rather than sit in a box!
All you do is add the stay on cover and your sorted :)
Perfect, everything works just fine
This scope has stunning optics that are extremely clean
