iPhone USB Flash Drive, 3 in 1 OTG Memory Stick USB 3.0 External Storage Expansion Adapter for iPhone, iPad, MacBook iOS Android Cell Phone PC（Gold 32G）

Just what I expected. Easy to download pictures from my phone and store them elsewhere.

So, I don't understand why an app is necessary, but it works. Download the app, plug in the device, and open the app. At the photo tab, tap the 3 vertical dots at the top right and tap select, then select all, then at the bottom left is two half arrows pointing left and right: tap it, then copy to USB. I'm assuming it's the same for the other tabs.The instructions that came with it aren't the best, but it's doable, considering I hate apple, don't use one, and did this for my wife who has an iPhone.

The other review that said the instructions are hard to follow is correct. When I tried to backup my photos the first time it didn't transfer them to the USB so I had to transfer around 400 photos and videos 5 photos at a time, and 1 video at a time. But once I did that, I formatted the USB on my computer and when I used it again to transfer more pics, I just pressed backup photos to USB and it did it all at once and quickly! So it does work, just takes a while to figure out.

Easy to back photos up from phone - have not tried on on iPad yet but hopefully it will move PDF files as well

gave it to my grandchild

Fast, easy, dependable, quite a bit of storage. I love this!

This item is easy to use. Plug it into your smart phone and install the app, and walk away. It stores all of your pics, videos, contacts, etc. Great deal for under $20.

Amazing product! works with iphone X
