Since that time the price was very low here, I have min. 10 units bought and am for min. 2 years no longer forced to buy more expensive Display Polish. Personally, I very often use this product for polishing the cheap and weathered Gartnlampensonnenkollektorem - the areas are like new and generating electricity again as before. Regarding mobile displays I am careful because I already had to replace the front here: there is, however, only the execution of the display to blame, or a particular layer of the display.
