The installation and working of the charger are both great! I have to say that the disappointing part of the process for me was making the application online and the follow up of that - or should I say lack thereof. Having completed the online survey I received an automated acknowledgement that it had been received and then heard nothing for a week - after which I sent an e-mail to customer services. Another week went by and still no response and so I sent a second e-mail. I stuck with it out of loyalty as I work for bp - but if I didn't I think at that point I would have taken my business elsewhere.
