The Pentalobe fits and the iPhone 4 could be opened quickly without problems, then the Iphone 5 this was complicated.
The suction cup which for opening the iPhone 5 is relevant was unfortunately very small and weak, which has greatly delayed the opening.
However, I also was able to open the 5 Series model with this tool kit and am very satisfied basically.
The processing of the tools is relatively good and even after prolonged use is no wear on filigrees Pentalobe profile to see.
The delivery went smoothly and relatively quickly.
A side note: If you are working as battery replacement it is advisable to clarify whether a tool is shipped with, because most of the suitable Petalobe and a small cross at least there, who could not, however, approach the quality of this tool set by far.
Conclusion: If you do not only work on a unique Iphone intends should consider buying this kit contemplated.
