There aren't many options for a USB hub, but there are three USB ports. All work very well. I used the micro SD and SD card slots because I often transfer pictures and files. They all work fine. The USB hub fits perfectly in the box without damaging the hub when removing it. I saw that they are too tight and I don't want to return them. I also had to open the box to get it. Love the fact that I didn't download the app to use it, which happened before me. The price is very cheap, but there is no cheap feeling, the quality is very good. The hub is small so I can travel with it.
