How much per wago is it? I have used about a handful in my time but don't like them. Seems to make a joint very expensive after faffing around and putting them inside a box. They are really only meant for inaccessible maintenance-free locations aren't they? Can't justify using them anywhere else, tbh. 5A or 15A connector block inside a chocbox is quick and cheap and they can be undone and re-used at a later date.
