They are a bit larger and definitely more expensive than the classic clips, but they are very practical and hold well. The quality is very good.
One negative aspect is that the contacts are very deep (1.5-2cm) and you can't see with the naked eye if the wire has reached the point where it should be attached or if you have also inserted the cable. You do it a bit blindly and hope for the best

They may be expensive, these wago style, but they are practical for us and for customers who pay correctly, want the best, and are regular with upgrades, it is what they deserve
