"If there was ever an invention that makes life easier its these things. That said, to make them work properly and get a quick neat result, you do need a decent pair of insulation strippers to get consistent 9-10mm ends like the CK 97204 or Knipex 6629F
And don't forget your Wago Boxes although a zip tie to keep your cable groups together will do if space is limited."
"I was introduced to the Wago connectors by an electrician and found the best deal on Screwfix, with all types available. I ordered a box set and it was well packed and delivered the next day. I would recommend these for ease of use in connecting multiple wires especially by light fittings,ratgher than chocblocks, and their availability from a Screwfix near you."
