The system was hard-wired to a dedicated circuit at my distribution panel. I can add a NEMA plug/cable if desired to connect to a 10/30 or 14/30 receptacle. You may also buy my OberSwitcher to share an existing dryer wall outlet with automatic charging when the dryer is not running.
Due to size and weight local pick-up only. I can help with installation.
I will not directly comment on the price as people can make their own judgments, but as a long time owner, I can give a little more info.
I have had one since 2011 and it is certainly functional although it's a big beast. You can manage it through the on-screen interface, over the local network from a browser, or through an account at http://www.blinknetwork.com
using either the ethernet port (recommended) or over WiFi. It logs all usage to your account and I can still access all my charging records going back to 2011. Blink would need to cooperate with transferring the unit to the new owner's account for the cloud functions to work properly.
Just for clarification, that unit technically requires a 40a circuit and charges at 30a. However, all of the units were remotely set to 16a by Blink because the handles had a tendency to melt when used at 30a (something that wasn't discovered for a few years as all the initial owners had LEAFs or Volts that only charged at 16a). There's a hidden menu that will let you override and set the amperage (under <= 30a). I replaced the cable and handle on mine several years ago, so I've confidently set mine back to 30a. Since the seller said he's charging at 6.6kW, he's obviously set his higher than 16a, too.
