I used a Henge vertical doc on my 2015 MBP, worked well and the design is really nice. The benefit, of course, is that the footprint is small. The downside that has stopped me using it is that you need to remove the device from the dock and open it to get it started up then close and put it back in the dock. Minor I suppose but a hassle nonetheless if you are doing it often.
Strange. I used a Henge vertical on my late-October 2013 15" MBP for four years and never once had to do this. I just closed it, pushed it in, made sure it was seated firmly, and then did some random taps on my external (both bluetooth) touchpad and/or keyboard. It almost always fired right up, although sometimes it could take as much as thirty seconds before both screens came to life.
VERY occasionally it would fail to "see" one of the monitors, and I'd have to pull it out, open it up, and then start the process over again. But that only happened a few times over the years. What was much more common for me was that I wouldn't get it seated firmly enough for both monitor cables or the magsafe to connect properly. The friction screw design of that dock also meant its connectors would slowly get pushed down to the point they wouldn't connect properly at all until I got out the right sized Allen key to reposition everything.
But that was it. 99% of the time I dropped it in and after a few moments it'd fire right up. Maybe it was my bluetooth stuff?
I got the redesigned one for my new 2018 MBP and like it a lot. Again, I don't do anything special to get it working, just close the MBP, drop it in, and I'm good to go.
The 2 USB-C connectors are permanently mounted, so they can't be pushed out of position. It wakes up and synchs to the monitors a lot faster, too. Great product!
