Since you have to watch ...

... That the little thing does not lose!
The card receiver is about fiddly, but how could that be otherwise, in these dimensions.
The micro SD card is clean in the adapter, this has the only 3mm constructive "hand grip" a small notch that makes it easier to pull the stick back out of the USB port. The adapter itself sits ebefalls well into the USB ports.
The blue LED in the "handle" is a matter of taste. I will light too bright.
