I have owned Tasco Scopes all my life.  I bought this one based on a friends recommendation.  The optics are very clear.  I did notice that when on the higher power (9x) just a little distortion on the extreme outsides of view.  Really, nothing that is enough to make this a deal breaker ESPECIALLY at this price point.  My friend has his on a 30-06. He reported no scope creep.  I have this mounted on a .22.  I would not think there would be enough vibration from a .22 to cause that.  1 zeroed in at 30 yards.  after 100 rounds, and a grouping within a dime, I can safely say no scope creep on my .22.  Again, for this price point, you can't get a better scope.  Bottom line, I would recommend this scope to both friends and family.
