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.

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 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.

Excellent quality, great price
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.

Very handy kit to have around.
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.

Satisfied
Rebuilding a 1949 mercury works perfectly for the project

These are mediocre at best.
I bought these to have a large assortment of waterproof connectors but several of these terminals have very thin and short barrels for crimping. So even if you crimp with a quality tool such as stakon or greenlee, the metal is so thin wires can easily pull out of the crimped barrels. Not all of the connector assortments are thin but many are.
