I think this device is brilliant.
I have never used all the features on my phones before now because I found adding/copying files too time consuming and often tricky to set up (I'm lazy and a tad technophobic so if it isn't straightforward I won't do it)
This device solves all those problems for me. There is no software needed for simple uploading of pictures and copying/transfering, and the USB means that it can be done without the hassle of wires, anywhere.
It is also inexpensive, so I now have a backup.
