Congrats on your Twizy! Your gonna love it.
One thing to bear in mind when using the Symphony Lead is that some charge points won’t release the lead. Basically you need to be very careful to use the charge points you can either terminate the charge with an app or an RFID card. Pod point charge points have proved a problem for me and I’ve had my lead locked in the charge point. I ended up having to leave it there and then contact the security company that manages the car park in order to retrieve the lead.
I’m not sure where you are in the U.K. but I have a polar card which costs about £7 per month, this allows you to use a lot of charge points operated mainly by ChargeMaster. These are good because you tap the card to start the charge and then tap it again to stop the charge, it then releases your lead.
