E-Z Red (PP12PK) Battery Brush

Product as ordered except, it arrived 4 days earlier than expected. Good on the seller for that.I have used these brushes before without any issues. Have always lasted longer than expected. I am a fleet Mechanic for delivery tractor/trailers with lift gates. Using only a single group 31 brush, I have cleaned battery terminals and cable ends for more than 6 months at a time, with no less than 5 PM's a week, 3 batteries per tractor and 2 per trailer. Only use genuine EZ Red brushes though. Generics break within a week, if not a couple of days.
