Product quality (good quality plastic). Very strong and quicker to put the screws to electrical sugars. I set 1:20 to ask 150wago counting the time to strip the son. Of the 2 100 packs ordered, none had the right number of wago. Always 100 in total but in the first, I had 61x3 and 19x2 entries entries. In the second, I had 58x3 23x inputs and 2 inputs. It does not matter for me but if you need exactly the right number of wago, it may hold surprises.
