I bought this kit to use with my laptop when dissassembling it.
I was able to remove every type of screw with these screwheads with ease, and put them back in fairly easily too.
It is magnetic but not very strong so it is still very possible to accidentally drop tiny screws inside the device which can be a nuisance to get out so care still needs to be taken.
The pry tools are also useful but only good for a few uses as the plastic is quite flimsy.
Nonetheless the metal screwdriver heads are good quality, and the other little metal tools are useful for a number of purposes.
The carry case is very practical too, I just wish the heads were numbered so that if you have a few out at once you don't forget where they go. You can work it out by looking at them very closely but this takes time, so would be nice if they were numbered or colour coded but that's just me being nitpicky.
