Full of qualities but a big flaw!

This drive is full of qualities, I will not go above but suffers from a big problem dergonomie, the wheel you might expect tactile (like an iPod) is actually a notched thumbwheel, the manufacturing quality of this wheel is questionable, indeed, it jumps more lines in the menu, or simply do not work!
A problem disqualifying for a product we use every day.

The chances that the wheel is "done" are minimal, there is a greater chance that it deteriorates ...

Do not buy!
