The blue small cloth is useless - it loses lint and smeared rather than it cleans. Since helping ordinary microfiber cloths from the supermarket more. ;)
The pen is very comfortable to hold and is now my main input device while the film does what it should - protect. It is very robust and I could not detect any color deviations.
A highly recommended product, despite cloth I forgive 5 stars because the film and the pen are really very good!
