Yes Ed you’re correct. The triangles are a lot softer so I tend to use the sticks to start the process and you can also get more leverage on them. The other really useful tool is the small point (by the suction cup) which is great for pressing reset buttons and getting sim trays open.
The cheaper consumer devices really are brute force jobs. Some of the better engineered laptops, like my Lenovo ThinkBook, can be very difficult to start but then come part easily. Then you get kit aimed at Corporates where no tools are required at all (or only a screwdriver) and the internals are sensibly laid out, like HP Probooks.
What I do find a waste of time are Corporate desktops with bits that fold out or hinge up or slide in. IMO they just make things fiddly. Don’t get me started on Dell where to add a second hard drive you find you need a plastic tray that isn’t included.
