I love this product very much...it does a great job on the computer screen it leaves no streaks just a nice clean screen...I also use it on my eye glasses and wow I was shocked at how clean they tuned out...it was so clear with no streaks any place...it was like the lens vanished they were so clean...I would recommend this product to anyone especially if they ware eye glasses... I would give it a total of 10 stars because it keeps my eye glasses so clean for me... MissKittyKat in California
