Do not go with Asus Transformer TF300TG! Have tested two TF300TG. But it seems reasonably to run in the Galaxy Note 10.1: Every now and then crashes that do not occur when taking the SD card out again - but it can be even even at that one tablet. The Asus Transformer just stops as soon as you plug in the card. After about 1 minute the Tabler responded again, but sometimes starts just too new. In no event the card is recognized in any way! Apparently it is not the controller, which is installed in the Asus, compatible.
I find it weak that neither supplier makes any information on compatibility in this regard! Interestingly, runs the card with adapter in the SD slot, the Asus additionally has the keyboard dock, properly. Nevertheless, I can not use because the slot is not available so, if you take the tablet from the dock the map.
Have a Samsung bought - works perfectly - in all devices!
