They really do work as advertised. No tricks or special techniques. When a few wires are coming together, I like using these where they are more compact, plus it is much easier to assemble with just 2 hands. I'm sure the pro electricians have no issue, but for the occassional DIY project, this makes my life easier.Big plus I learned that during a reno project where I have a lot of things temporarily put together . With these things, I can replace a switch in less than a minute an not have to deal with hassle of unwinding a twisted wire bundle.
