For aesthetics, the case lacks a coat of aluminum but we forgive him as he excels on the rest!
This dock accommodates 2 SATA drives, 2.5 "or 3.5" which is really a plus.
No worries ventilation, it is for my part store in a cabinet, and my office is in total silence!
I highly recommend this product even if it's a little expensive for an empty box :-)
bravo for this double bay dock thunderbolt.
Personally, no negative to date.
EDIT.
the transformer is a bit noisy (high, nothing serious frequency, but if you have it on your desk it will not TOTAL silence). at least I am accurate and you know all ^^
