I ordered a set. Got them brand new, but took them forever and ever to ship on a product they have overstock. Either way it was worth the wait. Great product. This will be my second set.
I looking for something that lets you set a starting and stopping point of lets say 600 miles. Then you tell the app your range like 200 miles per tank. Then the app will spit out the best places to stop for fuel along your route.
