I bought a Minox MD50 for my wife, but we never could get a sharp focus out of it. Sent it back (across the pond via San Antonio, TX.) About 2-3 months later, a new one arrived in the mail. I sold it - never got it out of the package. I really liked the size/weight, but finding out after I purchased it that it was yet another Chinese-outsourced product, my enthusiasm waned a bit. My history with the dependability of such units has been dismal. We are both now very happy with our Leupold Gold Ring Compact 15-30x50mm spotters. A tad bigger/heavier than the Minox, but [to me] clarity and build quality are not in the same league.
