Isnt it a bit misleading to claim two Thunderbolt 2 "expansion ports"? One of them is an input from your computer isn't it? So there is no expansion of thunderbolt at all, just one port out for one port in (daisy chaining).

But the idea is like SCSI or Firewire. Every device should have 2 ports, one for input, one for output, meaning there will never be a lack of ports in any configuration. But of course, some devices like to ruin the fun by being an unwanted cul de sac.
 
Any reviews on this so far? Doesn't sound like it, if it's just now shipping, but I'm curious to know.

I got mine a couple of weeks ago. Had to send it back and waiting for new unit. First, I go from 15"rMBP to home-theater receiver to Sony 4K TV. Worked fine direct, but with OWC Dock, I could only get stereo sound and didn't hear the surround channels. Also, after a few days, I couldn't get 4K video to work anymore even though it was fine at first.

Also, as others have also seen, I would get frequent problems when docking/undocking where the rMBP was frozen and/or black screen and needed a hard restart :(

OWC support claims these should both work so they sent me an RMA for an exchange. It took them several days to verify that the unit correctly works with multi-channel sound and had to have an engineer try it out. It's not in their specs and no one at OWC ever thought of this :(

I need to bug them and see when I'm getting the new unit.

I just got mine yesterday. Seems to work fairly well, but a few concerns that I need to work through over the next few days to determine if I will keep it.

1. As David pointed out, the audio appears to be all set to Line level. Not a huge deal, but there is noticeable difference.

2. Audio pops repeatedly when computer is sleeping. It makes a large pop noise every few minutes. I need to try a separate set of speakers.

3. Restart required to send screen to external monitor. This is HUGE. I really don't want to have to restart every time to get my screen to come back up.

I hope some other folks will be able to contribute about their dock soon.
 
Thunderbolt only supports one monitor via an HDMI or Mini-Display adapter. To use two monitors off of this Thunderbolt Dock, you will need to use one through native Thunderbolt and one through the HDMI port.
 
I just received my OWC Thunderbolt 2 dock from the new batch that started shipping on the 19th and so far am having a lot of problems.

1) My Mobius 5 bay JBOD USB3 enclosure connected to the dock keeps ejecting the disks

2) My two Buffalo Blu-Ray drives just disappear - they no longer show in the menu bar eject list

3) Weird errors with iTunes connected devices vis the dock. Trying to synch with a device connected via the OWC fails saying that my Promise disk (connected directly to a MacPro thunderbolt port) isn't connected. Well, it is connected. It is in the finder, and I can open files in it.

Pulling the power restores things for a while sometimes, then it starts all over again. Reboot does the same.

Anyone else having problems?
 
My first unit was sent out early Feb and it had lots of problems. I contacted support and they just said to send it back. They didn't do any troubleshooting beyond the turning it off and on again. So I imagine they were aware of common issues with the batch in question.

I got the replacement a while back and it has been working just fine.

It may have been they had some initial quality control issues which have now been resolved (hopefully).
