540PCS Marine Grade Heat Shrink Wire Connectors - Sopoby Electrical Connectors Kit of Tinned Red Copper, AWG 22-10 Waterproof Crimp connectors terminals Insulated Ring Fork Spade Butt Splices

They crimp good and are made well. I had a box of Kuject connectors, which are flimsy, resulting in at least a 30% failure rate when crimping, the wire came out easily. Then I got these the Sopoby and they work great. I threw all the Kuject ones away. In the picture you see the two side by side with the insulation removed. The Sopoby is on the right and as you can see is much more solid.

The connectors are really nice. They crimp beautifully (with the correct heat-shrink connector jaws) They crimp down tightly and heat-shrink nice and tight. They make for a beautiful and neat wiring job. I recommend purchasing a decent crimper set with at least 3 jaws/crimp types...sleeveless, nylon, heat shrink. You can pick a set up hear on Amazon for a reasonable price. I ordered the KF CPTEC Crimping Tool Set 7PCS for about $40. If you only intend to crimp heat-shrink connectors there is an option for just that jaw set and crimper for $17. Don't go cheapo and try using a regular crimper, it will show. My only issue with this set is the case which is quite cheesey but easily remedyed by purchasing a better quality box for very little. I just so happen to have a half-dozen or so that I picked up at Academy in the fishing dept.

I took a chance and bought these for use on a sailboat that lives in salt water. Normally I buy Ancor connectors since they are the absolute highest quality available but they are also extremely expensive. The metal connectors in this kit are not quite as heavy duty as the Ancor ones but they are close and the adhesive lined, heavy duty heat shrink is identical. For the price these connectors are exceptionally high quality and a much better value than Ancor for most electrical tasks. If you need some high quality marine rated electrical connectors I would highly recommend these.

Ok 👍 but kinda flimsy

great value instead of buying small packs at your local auto parts store.

Seems to be good quality and a wide variety of sizes. Purchased for one small job and have gone back to the kit many times since on other projects.

Rebuilding a 1949 mercury works perfectly for the project

Nice set. Love the heat shrink stuff. I don’t have to add any extra tubing to them.

Work great, happy to have this kit.

Great product for when you don't have solder gun near. Heat gun is all you need. The seal is nice.

Great kit for my applications around boat, vehicles and trailers. My only snowflake complaint is that the shafts inside the blade connectors is quite short for applications with recessed blades (e.g. alternator), as pulling them out destroys them. Other than that great kit to have around.

Excellent kit tres complet!!!

Arrived ahead of time. Items were as advertised.
