The Lexar does its work very, very well. The card snap a clean and USB3.0 is not to be sneezed at in conjunction with my Transcend 400x, it load the images rapidly on the Mac. Also no trace of the above-described dropouts.
A star deduction I give only a little shaky for USB connection on the card reader. Although currently this does not affect the reliability of transmission, for such a high-priced readers but not beautiful. A plus point there but for the included silicone cover that protects the card slot during transport against dust and dirt.
Conclusion: For me one of the best CF card reader on the market!
