Interesting to hear from another customer that their unit failed after a year. I have had exactly the same issue at just over a year. The unit (when working) is great. I have the 7.2kWh model which charges my VW GTE PHEV in a couple of hours. However it has recently developed an intermittent fault which is increasing its unreliability. Customer service seem to be responsive enough, as my installer has confirmed they will be replacing the unit, but unless they have made any recent design improvements, I fear another failure in the future. Not great if you own a purely electric vehicle...
