I've had mine for a while now and never had a moments problem with it.
It doesn't quite pull down to 10yds on full mag but will hit 12. At 25 it's as crisp as some more expensive scopes I've tried. It's possible the scope is faulty, it happens.
As Tourneysteve said they're a great budget FT scope.
I see this 'review' is a few weeks old now so what was the outcome?
