ZYAMY50pcs Scotch Lock Quick Splice Wire Terminals Cold Pressed Insulated Snap Lock Electric Wire Crimp Connectors Cable Joiner Red for AWG 16-22

I used these in wiring up a Lionel train layout. I used (or in some cases destroyed) all 50 of them. Over all I was pretty happy with them. I had never used these before. I had always done "home run" wiring to traditional screw type terminal posts. This time I ran power "busses" around the table and attached track and accessories to the "bus" by using these connectors. The only connection problems I ran into was when I was trying to use "speaker wire". I'd split the two wire cord but the insulation on that wire was "rubbery" and several times I did not get a good connection and had to cut off the device wire and use two new connectors on the bus. Over all I found it a lot easier than stripping, crimping, soldering and screwing the connections together.

no complaints, used this to wire my headlights and they worked perfect.

Great product

The slot for the through wire is too small even for 22 gauge. It's supposed to be gig enough for 22. I had to spread it with a screwdriver blade to get it around a 22 gauge wire. The hole for the dropper wire has only a partial stop. The dropper wire slides on through. The metal piercer will not clamp down flush with the body. All in all, a piece of junk.

This product is very difficult to use. The amount of pressure that is required to snap the device closed makes it nearly impossible to hold smaller gauge wires in place with one hand. Once closed, the device does a poor job of clamping the wires down and holding them in place. Overall, this is a poorly designed product using substandard materials. You are better off using wire nuts or a terminal block.

Used these to install some patio lights. The plastic is a little bit stiff which made it slightly difficult to slip it over the wire. After crimping the wires it locked in place and everything worked great. The price was greatAnd I would buy them again.

These look like the 3M product but are a poor copy. They are very difficult to use and will not work with 16 and 14 gauge wire as they should. I was able to use there with 18 gauge wire with much wrangling. I ended up taking most of these to Goodwill and reordering the real 3M connectors.

work as they should
