I bought this USB OTG stick to. Allow for easy data transfer to my Samsung Tab without Bluetooth or a USB cable to use. He has fully fulfilled this purpose. However, it should be noted at this point that the size of the stick for some people could be a problem. Since it is very small (the size of a laptop Bluetooth adapter) it is more difficult to act. And what would be nice if the stick would get a cap. But that is not even listed in the product description and therefore can not be listed as a negative. Just as a note for the manufacturer. Shipping and packaging were as always exemplary.
