This type in use at my condo (from previous owner era, and we also used it for over a decade) should be ~20 years now and still going strong.
Basically it mounts using some sort of sleeve anchor, which easily tahan few hundred kg each, but sleeve anchor in brickwall must be SPACED out from each other + positioned inside enough from edges, else cannot tahan.
There is some issue with brickwall as bricks are not 100% solid, they have holes and voids in the bricks (depending on pattern), and also length of anchor need to be long enough to account for the first 1cm or so is "useless" plaster.QUOTE
Too many fixings, spaced too closely together, can actually reduce the holding power. They should be spaced a minimum of ten anchor diameters apart and be no closer than five diameters from an unsupported edge.

It is also recommended to use a SDS rotary hammer if you are on
concrete wall. SDS rotohammer drill straight and true "circle"

whereas impact drill with "toy hammer" tend to snake (not straight) and/or makes oval holes which reduce the ability of the anchor.
