So you paid about $150.00 out the door. How much more would you have been willing to pay for it if it didn't cause you any grief?
I'm guessing you'd been happy at $175.00 or even more if it functioned to your satisfaction.
I've had little luck with new scopes that were less than $225.00, but there have been some exceptions.
I wonder if your problem was a fluke or if there's been a bunch of those scopes with similar problems?
