Goupchn 4mm Stackable Shrouded Banana Plugs Safety Fully Insulated Solderless Screw Fixation DIY Connectors 5 Colors

High quality, works great. Did use a dab of solder after modifying a couple circuit testers for posterity. Also made some tests lights out of 194, 1157, and H11 sockets. This is a true 5 star product.

These are the best ones in my opinion. Fit and finish is good and the set screw attachment method is way better than the solder on. Seem to be great quality and easy to use. Function well with a solid connection using a oscilloscope. For a few pennies more, these are the best value.

Used them to make custom test leads for automotive applications. Nice design. Easy to use.

A nice kit. The quality of the metal banana plugs was good and the plastic quality on the insulating housings was very good. Unfortunately, I found one of the banana plugs didn't have the screw hole fully threaded, so I can't use the screw to secure the wire in that one plug. Not a huge deal - I'll just use solder on that one, and it leaves me with a spare screw for the other nine should one get lost. But if you need exactly 10 (I needed 2 for an immediate project) and soldering isn't an option for you, you might want to buy an extra set.

These are the best ones available. I'm very happy with these, especially being stackable. The screws work great. I got these with a roll of silicone wire so I can crimp on my own terminal ends like duetz, weather pack, etc

Very good 👍

I really like these and used them to make up test jumpers and test lights. Having these makes it quick and easy to swap around and use various test leads when troubleshooting. I use them when troubleshooting electrical problems on cars, atv, lawnmowers and other things.

These connectors and the test leads you make will improve your efficiency on any diagnostic job. Having the ability to create your own test leads and test lights that all fit together easily is a huge benefit. I use these test leads often, and have had no issues with connections or voltage drop. I am an automotive diagnostic tech and need good equipment. This is good equipment that's not expensive.

If you do a lot of electrical testing and work, then these are great. Plan on buying more when I get time to build my multi-voltage test box

Súper!

When installing the wire screw. Too loose and the wire falls out and too tight the screw breaks and can't remove after that. Not very good quality.
