I received my dock yesterday and have been using it since it arrived. Here are my concerns.
The item comes with no cable. That is weird for a charger and something of this cost. Pretty cheap on their part.
The audio port works well, but I think that bluetooth sounds better, but this is not a major issue.
My biggest concern here is that it appears as if the pogo pins, used for charging and audio in the dock, do not appear to be charging the device at the rapid rate that the charger does by itself. I can plug the charging cable into the Nexus directly and recharge it in an hour or 2.
When I placed the Nexus in the dock last night, it was docked properly and showed the daydream screens, but it did not charge fully. It was actually losing power slowly while docked.
I might be missing something here, but the charging does not work well. I am charging it with the cable directly right now and will re-dock it after to see what happens, but I am skeptical on whether this thing is worth it at all.
I will update if I can determine what the issue is.
Hope this helps.
