I bought a cable to 100m at Konig and I was very happy. So I bought these connectors with their sleeves. The problem is that the sleeves are struggling to put the connectors in immediately when you press the bubble sleeve top (see image), plastic bucket on the sides. Looks like the sleeves have not been made to these connectors. The connectors work well. No problem to crimp but not professional result if it is a patch cable that "we will need to disconnect and which can slide the sleeve of the connector.
