Review on Karcy Caravan Disconnect Connectors 10 16AWG by Andrew Agarwal

We bought 4 pairs of these and they didn't fold up from a small zipped bag. Tried to use connectors and then push together and not go. There is no manual or online help. Please advise. They look good, but you have to make them work. 02/27/2019 I finally understood how they fit together. 1. You cannot assemble until you have installed all four contacts. I broke one while trying to figure it out. Once I've done that, they work great. It would be nice if instructions were included with the product. I am changing my rating to 4 stars due to the lack of instructions.
