As obsidian1200 said I also have never heard of the brand and you are probably better off shelling out the extra cash for a well known brand such as Spigen SGP. SGP are known for there awesome and easy screen shields and come with all the necessary tools to do it right, although they do cost a fair bit more then the average screen shield its worth it. When installing the shield yourself just make sure you do some independent research on how to apply them and make sure you don't press to hard on the screen when getting rid of the bubbles with the card, and its not a bad idea to have some Scotch sticky tape on hand so that any dust that may get onto the screen protector when installing can be removed, just lift the screen protector up and remove the dust with the sticky tape. You actually might be able to buy the screen shield and go into a Apple store and see if one of the many employees can install it for you. Good luck.
