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

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

### ⭐⭐⭐⭐⭐ Nice Quality Excellent Sealing With Shirnk
*by W***J on August 25, 2023*

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.
