Somewhere around 2 dozen Vari-X III, VX-III and VX-3's over the past 30 plus years. Never a failure of any kind.
Maybe the 3i is not up to par, never held one. When they came out and the price went down $100, I stocked up on 3's.
But ya know, it's the internet, so if 9 people have had a problem with a Leupold in the past few years and ran to the fire to whine and moan about it, I guess every dam one of the millions they've ever made have been bad.
