I've had four. Three 3-9X40 MC #20, one 4X32 MC #20. Two of the 3-9x40s went paws up. One I sent back to Zeiss. They promptly replaced it with a 3-9 TERRA. Sold the TERRA. One 3-9X40 showed up DOA, would not track horizontally. Returned for a refund.
The other two worked as expected. The 4X32 I have sold, but it was a nice scope just moved on. One 3-9X40 MC is still in service on a Ruger No.1 .257 Roberts.
Just my experience with ZEISS.
