Gives you the freedom to use as many micro sd cards as you want. Simple to use and works perfectly with my iPhone. You just download the leef app from the App Sore from Apple. Every time you connect the leef iaccess it opens the Leef app on your iPhone Gives you the option to transfer photos, videos and music from iPhone to memory card. Fantastic device 👍😁👍
Nice easy design , when you download the app you get not available in your country, but a bit of searching and you can find the right app , the instruction don’t mention this slight difficulty
If your computer savvy then it’s easy , if not you can be disappointed
