I've had several flash drives over the years, but this flash drive is by far the best. It is much different from any other USB Flash Drives that I own because for one, it is a universal 4-in-1 memory stick. It is compatible with any Android devices, iPhone, iPad, and PC for data Transfer & Storage. The great thing about this USB flash drive is that I have no problem in connecting it to my Samsung A5 phone. Thanks to the type C adapter that comes with it. Physically, it is small but it has a large storage space. 128Gig is a perfect size for all your file transfers or just mobile storage needs. So far it is holding up to my storage demands. Because I take a lot of pictures and videos of my 2 precious kids with my phone almost every day, I also get bombarded with "Storage Almost Full" notifications on my phone almost every day as well. I am really enjoying this flash drive because it really takes out the frustration of lack of space on my phone. I can now take more pictures and videos on my phone without worrying about not enough space because I can easily transfer and store it to my 128Gig flash drive in an instant. It operates on USB 3.0 which transfers large files very fast. This is a great flash drive that I carry with me every day along with my keys so I have it all the time. For the price, this is an excellent flash drive. So much storage for such a great price. I am very satisfied with my purchase, I love the color pink! and I highly recommend this flash drive to anyone looking for a fast and reliable storage device.
