I received my Nexdock XL last month. It appears very solid and well built. I had a UBPerfect mini before which worked well but it can only charge the phone with 500mA leading to the L5 battery additionally discharged (slower though). The ND XL provides up to 1000mA and after playing with it I can confirm that it did not discharge L5 battery.
Two problems though: when I connected it first it showed weird display settings without allowing to choose the best resolution. After a restart it showed the desired resolution, worked except the touchscreen. The phone though got very hot (flashing red LED) and after a shutdown the cold phone was “dead” - only reflashing would bring it back to life. After reflashing the phone the XL works as intended in convergence mode - except that the touchscreen is not working (it is not recognized in the mobile settings app either).
In a different post with specific gsettings command it was possible to have the peripheral touchscreen functional but I have not found the correct settings.
It is a bit disappointing that the convergence only seems to flawlessly work with a few selected models, thus more or less a limited convergence mode.
