I normally just purchase the cheapest or generic glass cleaner when I'm at the store. However, I had a coupon for Glass Plus with Jet Dry, and it ended up being cheaper than the store brand, so I bought it.

I have to say, I am sold on this product. In my living room, I have a beautiful glass top coffee table that unfortunately has more than a few deep scratches on the surface. I also have direct sunlight on the table part of the day and it really shows the scratches. After using the Glass Plus the scratches have practically disappeared and the glass seems much 'shinier'. I don't know if the Jet Dry fills in the scratches a bit or what, but I noticed a 100% improvement in the way the table looks. I also noticed how shiny and new my bathroom sink and fixtures look. No, I am not an employee of the company, but I do like to pass along information when I find a product that really does work. I love this stuff!
