Review: good quality - 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.
Review: Nice Quality Excellent Sealing With Shirnk - 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 desertcart 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.

## Questions & Answers

**Q: Are these terminals made of tinned copper?**
A: Yes, they are made of tinned copper and thick enough to do job. It also uses polyolefin, double wall, adhesive lined tubing.

**Q: Is there ribbs on the inside of the barrel or is it smooth?**
A: They are smooth. There's a tab on the inside to stop the wire from going all the way through. If crimped right and heat shrunk they won't pull apart

**Q: Are these made in the USA?**
A: No there made in China.

### ⭐⭐⭐⭐⭐ Excellent quality, great price
*by E***C on August 10, 2024*

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.
