I "took my chances" over the years with various other scopes, other than Leupold, and I was so discouraged each time that I always went back to Leupold and got to the point where that is the only brand scope I will buy.
It's just like I used to always buy Fords, all my life, brand new Ford cars and Ford trucks. Then I had a lemon of a brand-new T-Bird and Ford did not take care of me. I told a number of people at Ford that they would be losing a regular DEDICATED customer, they didn't care. So, since 2000, I have purchased a brand new Buick, a brand new GMC pickup truck a brand new Subaru and a Brand new GMC van!
Like I said, I will NEVER buy another Ford because they treated me wrongly.
I purchased a Tasco when they first came out and I could not get the crosshairs to move, then when they would finally move, I would be way off the target. After wasting about 50 .270 reloads, and unable to get the gun sighted in, I shipped the scope back with a long note explaining my problem. In about five weeks, I got it back, all excited and the job report stated they "tested it and the scope is fine - no work needed." I immediately sold it and bought a Leupold and never looked back.
As soon as I put the Leupold on my rifle, I went back to sight it in and within 10 shots, the scope was right on and never once moved after I had it sighted in!
