Review on MUYI 10 Kit – 2 Pin Way Waterproof Electrical Connector – 1.5mm Series Terminals – Water Resistant by Carlos Deuschle

They are really poor quality. I have the right crimping tool and a lot of experience with Weatherpack and Metripack terminals. They are not standard or interchangeable with OEM clamps and connectors. They are very difficult to assemble properly. The connector pins do not snap properly into the connector housings. There is no tooth to prevent the clamp from simply slipping out of the housing. If you want something cheap, consider buying a pre-assembled version of the pigtail rather than trying to assemble it yourself. If it really matters, get OEM style connectors and parts.
