You know me I bought it cause it was cheap, I just absolutely love cheap. I got this product at the local Dollar General early one morning when I was going to clean up my wife's car. The Professional Strength Glass Cleaner worked as good as the Windex I usually have on hand. I noticed that it smelled the same as the name brand only maybe stronger, so like always I had to try something. I poured half of the liquid in another container and added water to what was left and refilled the container, it still works just as good as it did before the cut. I guess you could do this with the other brands too but I like doubling up on the cheap stuff myself, it's like saving twice as much money. I would recommend this to others interested in saving a few cents, like me.
