Review on Qibaok Waterproof Electrical Automotive Connectors for Durable and Secure Connections by Carlos Phillips

I bought these to use on trailer cables. Trying to get them to crimp and keep the wire in the crimp was a waste of time (used crimping tools from my airplane maintenance job). Eventually, since I needed a connector, I just cut the "shrink tubing" and soldered the connectors on, then used my own heat shrink tubing. It was a huge waste of time and I would consider it rubbish!
