What is interesting is that the average rating is 4.11 but if you look at reviews for the last few weeks they are mainly one star. Let me add my one star (because i can give no less). Another mercedes 'free wall box' offer, captive audience. Took 10 weeks and was completed 6 weeks after the car arrived After all the forms and photos they sent a surveyor who just wanted to tell me it couldn't be done because of where the fusebox was. His suggested route before washing his hands of it was to take up all the carpets, floorboards and bathroom tiling upstairs. But even that i would need to sort as to protect their engineers they can't work at heights over 2m. So i found a local electrician, and a much more sensible route so £870 later there was a 32amp cable right where the box goes. I did very nearly give up even on the "free" box and head to plugitin.com. If you have a choice you know what not to do. Trustpilot reviews are even more shocking but I concur. I now need to share my thoughts with Mercedes re their choice of partner.
