Review on 10PCS Rhymad Conductor Compact Lever Connectors With Fixed Base, 28-12 AWG Electrical Wire Terminals For 2 Circuit Inline Splices (SPL-2) by Duane Barker

I just started using these as an alternative to wire nuts in our RV and I'm impressed! They really hold securely and seem to be well made. I saw a youtube video where someone measured the voltage drop compared to other connection methods and it is essentially the same as a butt crimp connector. I will continue to use these for inside connections. They are not appropriate for connections with any weather exposure.
