The thunderbolt dock 230W G2 works well when it works. We had several issues with configuration, but eventually got enough drivers, BIOS, and firmware to get it working. Seems to work OK except that the network connection is unstable.
I bought this hub to replace my older-model HP Thunderbolt hub which stopped being able to drive 3 displays at once from my G3 Z-Book. The monitors would randomly go blank and flash on and off. Intolerable. Unfortunately, after 2 weeks of use the new HP hub has the same problem.
The combo cable seems to be a great idea, in that you connect the USB-C port and the charging port together. The cable is a bit stiff, but hopefully in the long run this stiffness equates to longevity of the cable. The dock is fairly compact, but does have a bit of style to it. You do need to take care with the cables that plug in, as the dock can tip to the back with the weight of the cables if the cables are allowed to be dead weight.
This was installed on a computer on a domain network, and we quickly found out that the first login of the laptop after connecting to this dock needs to be made with an account with administrative privileges that already existed on the laptop. After this first login, several drivers are installed, including I believe the driver for the dock ethernet port.
We got the dock with the audio option, which had to be attached to the dock. There was even a screw driver included to take the original top off and replace it with the audio top. Based on the limited used so far, the audio quality seems to be fine. Just don't expect booming audio from a speaker this size.
Of course, only time will tell how durable the dock is, which it better be at this price point. Over it does seem to be a nice dock.
Great product, great features once you get it going. But do not expect to just hook it up and it to work immediately. If you are computer savvy and like a challenge, get it. Had to do several hours of research and troubleshooting before getting it to work properly every time. You must download several drivers, software, and firmware updates for this unit. Also some Bios settings must be properly selected for this to function correctly. Would be great if HP made some sort of bulletin on how to install all of the necessary settings....
I bought 3, one for myself and two others that have had docking station issues, hoping this newer model would be better, but it is worse. The screens blink badly on all three, and there is no solution for it. Checking online many others have had the same issue and apparently there is no solution.
