This iphone card reader is the perfect travel companion. After I downloaded the app from the QR code in the user manual, I have been able to do a lot of things with this little device, so far I have:
-Backed up my iphone pictures, video and contacts onto an SD card (using the app that came with it) -Reviewed on my phone my digital camera photos and videos from the SD card and copied them to my phone - emailed pictures from the SD card using the app that came with the device. - connected it to my laptop and read the sd card via the USB plug side (great) -Charged my iphone with the cable plugged into the laptop and a power brick. (but it does not act as a iphone data cable to connect to iTunes).
SPEED: The speed is similar to other USB card reading devices. I was able to backup my phone contacts, pictures and video files (over 1000 files - 5GB total of pictures and video) from my iphone 6 to my sd card using the device in 6 minutes.
DIRECT WRITE TO SD CARD from phone camera and microphone: Another interesting function I discovered is that when the device is plugged into my phone with a SD card in the device slot, I can take pictures and video using my phone and write directly to SD card bypassing my phones camera roll. - COOL! (I did this by using the app function / pushing the circle camera looking button in the app).
The build quality of the card reader feels a bit cheap (really light weight), while the quality of the cable section feels good. Functionally it is flawless and works brilliantly.
Overall this is one impressive little device and is great value for money, I would recommend this to anyone looking for a good backup / travel solution of this nature.
