- reliability of Ethernet upon connect/disconnect
100%
-- reliability of display port upon connect/disconnect
100%
-- charging speed
As fast as the adapter. It's 85w
-- any issues with USB-A devices and incompatibilities
No issues so far. I have a logitech webcam, an external 4tb HD for time machine, document scanner, and a wired keyboard connected. Everything works 100%

None
34" Dell U3415W on the TB3 port with a TB-Displayport cable and a Dell U2713HM on a direct displayport-displayport cable. No issues at all.
I'm quite pleased with it. Everything works exactly as advertised. I had an OWC on order since December and cancelled it once they verified that it wouldn't charge a 15". I ordered the elgato last Wednesday the 14th and had it on friday the 16th. OWC hasn't even shipped yet.
