I have several ZA 5 1 x 6's, 1.5 x 8's, and 2 x 10's. I bought these about 2 or 3 years ago and at the time I ranked them as the vest value per buck for my eyes. I have a 1 x 6 on a 375 Ruger with zero issues and I have had zero issues with any of them. Needless to say, I like them a lot to buy so many of them.
They are bright, clear, and quite usable scopes.
I have compared them with the Alpha glass on my other go-to rifles and during bright sunlight conditions, are not bad at all. Comparing the alpha glass scopes in low light conditions, like dusk and dawn, especially the S&B 8x56, there is a huge difference in visibility, like 15 minutes or so depending on the model.
