Solid construction!

By: sgto416 - 01/27/2019
The Thunderbolt 3 to eSATA Adapter + USB 3.1 (10Gbps) port works as it should - fast transfer rates. I did not have any eSATA devices to test but I did try the USB 3.1 and the transfer rates did not disappoint. The adapter does get warm but that is just from use. I received this product in exchange for an unbiased review.
