Zollotech posted a review of the CalDigit Thunderbolt 3 dock on their YouTube channel. It’s not really a review aiming for deep technical insights, merely an overview of the capabilities of Thunderbolt 3.
They do however at around 0:45 hold the dock in their hands, and that gives you a good impression on how compact this dock actually is.
As we mentioned in our Thunderbolt 3 dock overview, the unique thing about the CalDigit dock is that it sports two eSATA ports plus its design. The latter is well demonstrated here.
