I'm an electrician working on cars, caravans, plant, hgv's and have been for longer than I care to remember, I agree with the comment regarding banning scotch locks, I've no idea what these wago connectors are but I'd also think the OP is a distributor of them but regardless of whether they are I don't need to see them to have a pretty good idea that they are going to be a posh version of a scotch lock, might be slightly better quality but still a scotch lock basically and if so these should also be banned, why anyone doing electrical connections doesn't use a soldering iron when you can pick them up cheaply I don't know, I use a decent quality gas soldering iron that can cost me around £80/100 but will last for ages, for handyman jobs you could get one easily for less than £40/50 but will probably last you for years, scotch locks and probably wago connectors have a nasty habit of making and breaking electrical contact, imagine using them for tow hitch electrics and the connection to brake lights has been lost! If you want a proper job soldering is the only way to go.
