Follow up on my initial post (#4).
In addition to what I posted, which is that I have two of their sets and generally like them overall, one issue is with these interchangeable bit-type sets, ifixit or any others - which is that, due to the design of the interchangeable bits & the holder, they will not fit into deeper holes on some laptops to reach those screws that are deeply recessed into the case.
I find this to be a major drawback for these types of kits. I will probably purchase a multi-screwdriver set with long shanks at some point in the future & ditch the interchangeable ones.
