Review: Great value and verity. - Great selection. Very happy with the purchase.
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.

### ⭐⭐⭐⭐⭐ 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.
