(4 stars) Small, portable Thunderbolt 3 dock almost great

By:
I have to say I love docking stations...and overall I have had some great ones from StarTech.com. This one is no exception. It is small and portable with a good weight to it and they put rubber on the underside to help keep the dock in one place. The video resolutions are impressive and the device works effortlessly. Now is it perfect - no....there are some things I just dont get. One is a single usb 3.0 port and one Usb 2.0 port. At this point I would have just expected usb 3.0 ports and finally there is no Thunderbolt 3 port to daisy chain devices. This I would have expected especially since some computers are only coming with a single port. Overall this is great for someone with simple needs, I personally would rather have some of the more robust docks that startech.com makes. I received this product in exchange for an unbiased review.
