Review on Effortlessly Connect Your Wires With 20 PCS Pluggable Wire Connectors Kit: Hand-Protecting Push-In Lever Design For AWG 24-12 Electrical And Automotive Wiring by Adam Wilson

These connectors seemed to be the answer for wiring up LED lights on my UTV until I tried to use them. They may work good for small Chinese fingers, but are too difficult to manipulate with mine. First, they all came closed and the only instructions for opening them was "You will need a pocket knife or something to pop them open". I make it a practice to limit the use of sharp items when I get frustrated. And these connectors were definitely frustrating, especially if you are trying to insert individual wires as opposed to the twin wire red/black stuff. Also if you use wire with tough insulation they do not reliably cut thru the insulation and make contact with the wire. I purchased a roll 20GAWG twin wire from ebay that fell into this category and could not get them to work with this wire although they did work with other wire I had. Finally I gave up and threw them all in the trash and went back to using solder and shrink tubing.
