Very bad luck, in a concentrated form. In the 45+ years I have owned alpha glass, I have not had one issue, ever. I feel bad for you to have to down grade so much to a Leopold after spending so much on alpha glass.
Of all the scopes I ever I owned many of American origin, the only scope I consistently had issues with and gave up on was Leupolds.
You experience is very unusual.
Can’t say it was a downgrade as much as a failed upgrade. I’ve used Leupolds for decades…never had any trouble. But the glass on these newer scopes is another league. So I can stick it out a bit longer. I am surprised to have these issues. And the same basic function (illumination control) is falling on each. I really thought I had a bad run of batteries but that wasn’t it.
