Fit well and look good
I used these to wire cube lights on my truck. Working well.

Great part
Save the days when a fountain lamp needs replacement. Larger ones are better, but these can last up to a year, taped correctly to assist with water proofing.

Sturdy, effective, and stylish.
This product is exactly what I was looking for. I would however suggest applying a silicon jell if you are going to use these connectors outside. After I connected the wires, I applied a silicon jell to stop the wire from corroding and water accessing the wires.

Very nice design
I would give this product 5 Stars for idea and execution, but for some reason they do not include complete set of sealing rings for small diameter. So it will be 4 Stars than. I used this connector on boat for transducer spliced cable. There is very strict requirements for this setup. The signal is very high frequency and very weak, so connection should be absolutely flawless. Also is should be absolutely prof for water and engine room fumes. I had reservations at the beginning. but to my surprise it works very well. It works better than my heat shrink crimps (which I replaced with this one connector) . My transducer send very reliable signal now and I am very happy about this. It is very compact and light (which the reason I bought it in first place) and it has reasonable price. Vendor splice box about 10 times bigger and 10 times more expensive, just for doing exact the same job. One note. It has very small screw in a connector and it requires effort and time to align and secure wires.

Life saver for pool light
Seem to work well on my pool light. Life saver when the pool light wire is stuck in the pipe and can't be pulled out

Bulletproof underground and outside connectors
These are bulletproof wire connectors. I have mine underground snd it can get wet where they are after heavy rain but no problem with these. I did cover the connections with electrical grease and I hit the ends and middle outside with silicon chalk and let it dry before putting them underground. These are sturdy. They don’t break but of course no one is driving over them. I do with my tractor and there is no issue. Great product. I have used it several times on my property outside with underground wiring applications. Be sure your voltage and amps match the product.

Trop peu d’informations sur la compatibilité et la façon d’utiliser le produit avec le système électrique existant. L’étanchéité est inexistante. J’ai dû faire venir un électricien pour refaire les connections.

Si tiene uno la necesidad de poner una conexión exterior, será necesario protegerla de la intemperie y estos dispositivos lo hacen muy bien.
