MadShrimps posted a review on the Lexar JumpDrive M20 Mobile USB 3.0 Flash Drive
A quote from the article:
The last USB 3.0 OTG flash drives we have tested were sporting a smaller footprint and also needed extra protective covers for avoiding damages to their connectors. In this case, the chassis is indeed bigger but no extra accessories are needed, while we can switch from one interface to another just by working with the slider.Lexar JumpDrive M20 Mobile USB 3.0 Flash Drive Review @ Madshrimps
