Thank you for viewing. This is the Kensington Thunderbolt 3 Docking Station SD5200T. It's perfect for those using Thunderbolt 3 compatible PCs, such as MacBooks. With a single cable, you can simultaneously charge and output to dual monitors, keeping your desk tidy. I purchased it on Amazon a few years ago and used it without any problems until recently. I have reconfirmed its operation for this listing. There are minor scratches from normal use, but there are no noticeable scratches or stains, and it is in generally clean condition.
