3 2-7x33 Leupold VX-1's, 1 Leupold VX-2 2-7X33, 1 Leupold LPS 1.5-6X42, 1 Nikon Monarch 2-8X32, and a Zeiss Conquest 3-9X40. The Nikon I've had for less than a year but so far so good. The VX-1's I've had for several years with no problems. The VX-2 I've had for over a decade with no problems. The Zeiss and LPS are my favorite scopes. Great light gathering ability and clearity plus the Zeiss has a fixed 4" of eye relief at all magnifications.
