“Very pleased. Great idea for VPI to distribute this as a concentrate rather than ship large bottles around. It mixed up in a gallon of water in minutes as advertised. I have only cleaned a few records thus far but it worked great and left a very clean and quiet surface (seems to be a mild but very effective solution). My only question is that I mixed it in a gallon of pure distilled water. The label just said "water" so VPI might want to specify whether distilled water is preferred or necessary or if regular water is OK or recommended.”
