So far I have had only good experiences with Mumbi and already installed on many mobile phone models protectors. The first films were not properly applied, despite accurate work under the guidance and advice of Cell Now. That's what I as given in my review continues and the surprise was that I got sent to quality assurance, a revised version of the article ordered from me. Surprised me only the new packaging and the old who had the same EAN. The new film could be at the first attempt to raise decent and I feel very satisfied and the Smartphone again looks chic.
