At first, very bad experience:
Systematic wild ejection during the simultaneous connection of two External Hard Drives (obviously it does not have the electrical capacity).
But the problem is repeated with a single External Hard Drive: New wild ejection and, this time, loss of data ... (disc reformat)
the model I received may present, after all, a manufacturing defect ...
Hence a very negative comment ...
By cons, good responsiveness and attitude of customer service who contacted me and just sent me a new model.
To be continued ...
