My personal opinion:

I find the device Top and can only recommend it further for fast data exchange without extra to have a desktop PC in between.
The USB port for the mouse to work properly, a keyboard I have not since I already use a geteste via Bluetooth.
It is small and also a decent, robust impression.
MS Pro Duo and M2 slots are a bit old-fashioned because I have put these memory cards only in my PSP for my taste but still very good they fulfill their purpose if you want to take this.
What was also not easy at the insertion of microSD card.
You get the feeling the MicroSD card does not fit in there and only with a little violence where one actually already thinking "So now is the MicroSD card completely useless" it is properly connected and is recognized by the system drinne.

Despite the two three tiny flaws I give the unit 5 of 5 stars.
