    Got this for my IPhone, I thought I’d be able to move images by just polishing it in and downloading the app. It was not compatible and it was very disappointing. Not it’s just like any other USB that I have to plug into my computer along with my phone.

    The 256GB Ultra dual drive makes moving large amounts of photos and files to&from my Samsung phone and my Windows 10 computer. It's a compact and efficient design. It's enclosure and rotating cover are plastic and don't look all that durable compared to some of the metal drives I've owned, but I've not had any issues so far (I knew it was plastic before I purchased).
