The tool is hard to use. Except for the Pentalobe (5-star) are all enclosed screwdriver too big for the small iPhone screws. Who owns watchmaker tool or a screwdriver PH000 should get easily through the exchange as well. The remaining tools are for example, to replace the super suitable display.
Who it only on the battery arrive and still needs a favorable Pentalobe screwdriver that is the right place. The rest is unfortunately virtually unfit for battery replacement.
