I ordered this adapter to use it with my Nexus 7. My box being g wifi, the speed gain is really appreciable as I pass by ethernet. In addition, it allows to limit its exposure to the electromagnetic waves. Note that I had qques worries during initial testing due to a contact problem between the USB socket of my OTG cable and the adapter. After "tweaked" a little pin cable, no worries! The adapter discharge a little faster the battery, but hey, you can not have everything :)
