First the positives, the adapter as Amazon usual delivered next business day - exemplary. Now for the adapter. I wanted to use this adapter for my Galaxy Note 10.1, due to the overwhelmingly positive reviews and I wanted to read a USB stick or an SD card from my SLR camera every now and then. Now, the adapter I plugged and he has also been recognized immediately as a USB connector. Then I plugged in a USB flash drive (4GB, formatted in FAT32) - nothing !! Another stick tasted (8GB, also FAT32) - nothing !!! Then still plugged in an SD card - again nothing !! What helps me a seemingly correctly recognized adapter if the storage media then are not recognized? I have to say that the USB stick rather loosely plugged into the adapter., Which can be wiggling back and forth, which can not be normal. In contrast to the SD card slot, so you have to push in the SD card properly fixed so that one already believes that one wants to plug in upside down.
So as a part I really do not need, absolute cheap production, is now once again back, rather then having to go through the microSD slot in the tablet.
Maybe I was just unlucky enough to have caught a defective part, but absolutely cheap processing of the adapter has put me off so that I want to try no exchange.
