First everyone has understood it is a USB key with a wifi installed 32GB micro SD,
The interest is to enter its files by wifi, which is very intéréssant when there is no USB port on a tablet, for example, or simply with a mobile phone.
I liked the concept, the idea is not new but useful,
The look of the key is nice, except for the cap poses one particular problem.
The micro SD slot is seen, I have not tried the key with a greater than 32GB SD card but it remains to be seen ...
Once San Disk software installed it is very easy to pick up her files,
and that's when I start to talk about the disadvantages,
From that moment, more internet connection (with good tablet)
as it is a pity to have to choose one or the other of the possibilities ...
Simply put if I want to look at pictures on the wrench for example, I no longer access my mails in real time,
where if I want to listen to a music not surf the net, and so on.
Another disadvantage is the sliding cover, so the USB ports on the computer are few and close together, it is impossible to use the second port when the key is inserted ...
As I said I have not tried it with a larger capacity card, so I do not know if it would work with ....
To conclude
The key is good, the idea interesting and practical use,
I found other brands that do the same thing, plus a charger fontion and without losing the connection, so for me the use of this key is rather average,
Would recommend, however ...
