I have found they are great not only for tablets and phones, but also for monitors, TVs, and my sunglasses.

So many of the cloths are so small, I find it difficult some times to properly clean the surface. I have used this cloth on my phone, iPod, and my sunglasses.

It is a bigger size than a typical eyeglass cleaning cloth so it works really nicely on the ipad and laptop screens. I haven't had any smearing since using it and I haven't used any kind of cleaner with it. I have to use a spray cleaner with my other microfiber cloth I got from Costco. You can also wash these up if they get too dirty and it sells for a cheap price. I bought some that weren't as good for more money at Costco. These are softer and seem to clean better but neither brands scratched my items. If I need more, I wouldn't hesitate to get more of these. You can't beat the quality and price.This microfiber cleaning cloth works well on many surfaces including the screen of my phone, the lenses of glasses and sunglasses, the screen of my tablet computer, and even my glass mirror. In particular, my phone screen was very dirty with smudges when I decided to clean it using the cleaning cloth. While I did have to apply firm pressure while cleaning, I did not have to use anything other than the cloth to clean the screen. This is a great cleaning cloth.I received this product in exchange for my honest review.I just recieved this product & I must say it truely is amazing! Absolutely loved how it cleans my phone & tablet screens.
