The newer block dock requires less space than the original docks. I have had no problems with connections, with device communication, or device recognition. My complaint or suggestion is to remove the DP ports and add more USB-A and USB-C ports. I had to add a USB hub for the rest of my connections.
It has been years since I used a docking station and they have come a long way to todays product, which can handle 12 connections. The HP Thunderbolt Dock 280W G4 w/Combo Cable has operated without any problems and is far superior to any thing used prior to this. The thing I like most is the fact that all devices related to my computer connect to the dock directly and one switch controls all. PDMyers
