Level copy, you can copy from / to the SD card, USB or the phone. My Canon 700D is not recognized and my galaxy camera (USB) either (or in camera mode or in multimedia mode), so do not expect to use a camera as a USB card reader to a card to card copy.
Another disappointment, the application does not read RAW cannon devices (you can copy the files but not have preview), it would have been very useful to me to be able to view my pictures on my iphones and import ones I wanted to convert / edit and post them on facebook, kicking in RAW but this was not possible.
Otherwise copy works but it's not a lightning war, I would have paid 10 more to double the speed.
I has quickly tested network functions before leaving, it works (but I was restarting the obligee lite mobile to access my wifi, so it's not instant). The device can therefore serve as wifi repeater to home if you want to go into the garden for example. The wired connection is convenient for hostels with several floors, some of which are poorly covered by wifi.
The battery on it is correct, I have not emptied, so it is enough for me. Note that you can use it without starting completely mobile lite, you just make a quick press of the button on the LED flashes to indicate the charge status and starts charging your smartphone in passing.
You have basic functions via a web interface available on 192 168 201 254, that includes the main parameters (see image) and allows you to view / download online content (except phone), but not copied to the mobile lite. Also note that I have been able to access the USB port smb (no password, anyone who is over wifi access them). We can theoretically use the device in limited mode (no copy to the phone for example) without the application.
Level of improvement, I would have added a torch blade (LED) and a second USB port, an increase in copying speed would also have been appreciated and can be a more accurate battery indicator. And RAW mode would be great, å can get to work without looking at the camera and looking for the file name but it would be so much better if we could see them directly, and maybe even create a copy in jpeg passage (optional).
It would also have nothing against a decrease in the size (That a broader iphone 5 (1.5fois wider) for a similar length and double thick) offer various battery capacities might have been intelligent.
Overall the product is good considering the price.
