Key 32GB USB3 Very electrically correct, but poor design

Most:
Very good quality / price ratio for operation:
Transfer large files to speed USB3 Port: read 42MB / sec and 25MB / sec writing. On USB2 port: 25MB / sec read and 22MB / sec writing.
For 14 euros, it's rare to find writing rate as high.
Only in writing that the Corsair Survivor 32GB USB3 done better with 32MB / sec but costs more than 2 times the price.

The LESS:
Hard to insert, because it slides in its case to protect the connector (which is still not immune to dust) and that the judgment is not sufficient, then the connector returns it must firmly hold with your finger to force the insertion!
The sliding system makes it too large to place it in front when there is another USB connector on the next turn.
Another detail, the announced capacity is totally false: for 32 GB announced it is only 31.106 gigabytes counting in decimal, or 28.9 Gio.
