Offered here is brand new unopened/never used Dell SD25TB4 Thunderbolt 4 Docking Station with the power supply. It's a nice addition to Dell laptops, but it was purchased just before I decided to switch to an Apple Pro suite for my media editing and never needed it. Just been in the box and sitting on the bookcase shelf. It will be properly packed and shipped insured. Let me know if you have any questions and I'll try to answer. Thanks for looking!
