Ask HN: Searching a USB-C / Thunderbolt 3 Dock with 2 x 4K 60HZ

Hello, currently I'm searching the Internet for a USB-C or Thunderbolt 3 Dock which supports 2 Monitors (4k @ 60 hz) and some USB for mouse/keyboard.

Actually I use a Dell XPS 15 9550 and have a Dell TB Dock which is total crap since monitors stops working or USB doesn't work or whatever.

Somebody have had some luck with that yet?

Shipping to Europe (Germany) should be possible.
