Goupchn 4mm Stackable Shrouded Banana Plugs, 5 Colors 10PCS

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.

Rear-Entry screws for securing the wire (14g, in my case) work much better than side-set screws. Way much better. No crimping or cutting into wire, just a solid connection. Disclamer: I DID add a dot of solder, after cutting the wire flush, for conductivity... measuring mV, and wanted an accurate-as-possible reading. My leads (+/- 1 meter long) had 0.00 to 0.01 ohms resistance. Did not test with screw-attachment only (Bad Me... that is not very thorough), but I did inspect the wire, and give it a good tug... very acceptable. All plastic parts fit well with each other, and fit snugly into my DVOM, also. I will now look for as much rear-entry screwing as I can find. What?

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.

Work quite well.

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

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

Built 5 bypass test leads.for automotive diagnostics and they are so well made. Saved me hundreds comparing buying one bypass wire from Aeswave at $35 each that use pvc coated wire which is not good including there test leads from uTest kit which are also pvc coated wires.. I have used these to build automotive test light sets. They are really nice to work with and are very low ohms. If you need to build tedt lights, test leads, or bypass wires buy these it will save you hundreds plus you can use high quality silicon wire. I used up to.16 gauge.silicon with them. I wish other connectors where like these.

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.
