I fitted some of these on the living room wiring.

Screwfix ones shown as an example as I can't remember what ones I
actually fitted

Just lately one packed up all together and just today one of them feels
as if one of the USB sockets has physically given up the ghost.

I suspect these have broken as they were cheap is there any
recommendation on type to get for longevity.
