I've had a consistently unpleasant experience with these... even in our new build with perfectly solid plasterboard walls, they have a tendency to pull out and gouge huge holes in the wall. They also leave colossal holes (at least for the larger size ones) which are a pain to patch.
I've now replaced all of these (where they existed) in our house with hollow wall anchors. Much easier to set, much more solid.
The only comment with hollow wall anchors - which is obvious in hindsight, but not something I initially cottoned onto - is that they need at least the full depth of the anchor behind the plasterboard for them to seat properly, otherwise they just crush and collapse.
True, though I’ve managed to used them on external walls with dot & dab plasterboard by drilling into the block work behind to make sure they have room to seat before using the setting tool.
