Very correct kit for the price. I have not needed additional tools to change the screen of my LG Nexus 4. against two negatives: - The clip is really bad, not rigid enough and suddenly, does not pinch much. In short, it is unusable at once! - I'm not sure that the plastic used is resistant spatulas for a long time ... Well, it's not really bad because I do not count disassemble my laptop every day;) In conclusion, rather satisfied with the product but for that price, nespérez not professional equipment!
