had long, very long fight with me to make up my mind for this quite expensive disks concentrate. And stand today, I'll never use again another! Despite approximately 15000KM per year, enough for me a 5 liter canister for 2 Winter! Before that, I needed about 3-4 cans !!! You need the windshield wiper lever once and press the discs are streak-free clean! No matter how much Winterschmodder etc. is on the disc! Just awesome this stuff !!!!
