    Honestly, I do not like the design and it only fits my laptop and not my desktop. It is a very strangeUSB-C.

    It worked nice. I had to learn how to use it. I'm still not completely there. I got to read something I put down. To navigate. It could be a little easier for me. Trying to figure out how to print off it. And other things.

    I bought it because the phone doesn’t have memory slot. I got the great deal from Best Buy. But it was pretty slow to transfer. 60GB took me approximately 20-30 minutes.

    First time getting disappointed by sandisk usb sticks, my sandisk purchases have been great until I bought this usb stick. Whenever I move photos into this drive, not only it gets transferred slow, it overheats so bad so it won't accept photos and get stuck at loading.. if you are looking for big storage usb drives for you phone, look for other usb stick
