This is a great product and one I have been using for several years now.
I first learned of this product at the Apple Store and it is what they use to clean all of their computer screens and when they complete repairs. However this was about half the price of what I originally paid at the apple store.
I use this product to clean all sorts of screens. My two laptops, desktop monitor, lcd tv screens, iPod screens, cell phone screens, gps screens and I think a few more. No matter what the item I clean the results are the same and that is awesomness.
iKlear does a very good job of cleaning off all the dust, fingerprints, moisture spots, and any other crud off of your screens.
The included clothes do a great job of not scratching your screens and the liquid dries quickly. After a good clean your screen looks like it is brand new.
There are probably cheaper cleaning options out there but this one works so well it is the only one I will ever use. I recommend it to all my friends and family and they are always very satisfied.
