Quantaray is the Ritz and Wolf Camera store brand.
I have a few Sandisk Extreme Card Readers and Lexar Professional USB Card Readers, both USB 2.0 and USB 3.0 and have never had a problem with any of them. One of the Sandisk Extreme and one of the Lexar USB 2.0 Card Readers are over 7 years old now and they continue to work perfectly. Of course the latest USB 3.0 versions are significantly faster if your computer is so equipped. Good Luck and Enjoy your Nikons!
