I bought these to repair my iPhone 13 and I can't say they didn't do the job. Around the third time I opened the phone, the screwdriver (specifically the pentalobe) had worn down and stripped the screw head, rounding it off. In the end, the screw never came out.
In conclusion, if you want to use them once or twice, you can; if you want to use them more often, I don't recommend them. It would be better to invest €10 more in a complete screwdriver set.

Not even... I tried to open an iPhone 7 and ended up going to buy a screwdriver specifically for iPhones that is triangular. It didn't even open three screws and the tip broke. Just get a plain triangular one for 7 euros and that's it
