This was purchased as an after thought to fill an order to get free shipping. Turns out I didn't realize how much I needed a quality screen cleaner. With screens in the house ranging from the Big HDTV to Desktops to Tablets to the tiny Iphone, they all get smudged and grimy.. and this spray works very well at removing fingerprints, smudges and everyday grime. I'm satisfied with the quality and price of this
