I'm finding less and less need to check the ratings as things just seem to work more than they don't... Missed my preference for charging coming into Atlanta (was having a good conversation with our son based in San Diego so priorities) realized I needed a quick stop while in the middle of the city, hopped into Ford Nav chose chargers there was an EA nearby, went to the charger and while the screen wasn't working right (and the poor guy with a Tican was having issues and on the phone with EA mostly new user error) I plugged in and charged nicely... Now @Ford if you are getting rid of Nav you HAVE to allow us to find charging locations in Charge Assist WHILE driving! Charge Assist is so superior in listing charging stations but we need it while driving!
I"ve had some luck with chargefinder.com seems it has real time availability - at least it looks that way - I also use plugshare to see what has been reported on a location.
