Works great for installing wires into amplifiers and feeling secure about it .

Had all the sizes I needed at a good price. Would recommend

These are good quality.

Perfect for my own works

I honestLet didn’t have high expectations for these ferrules given the low price and obvious off-shore sourcing. But now that I’ve received them I gotta say I am very impressed! The look and feel great. I’m the photo you can see that I have installed them onto the ends of an 8” piece of high-end, 1/0 pure copper cable. They fit like a glove! This cable had previously been attached to a distribution block with set screws, so the ends were pretty gnarly. I was able to twist them down and get them into the 1/0 ferrules very cleanly. I would say that they are perfectly sized. I also love the range of sizes and quantities included in this kit.One thing to point out... I looked over a variety of ferrule kits. Nearly all of them are sourced from China, and nearly all of them list “#1” gauge wire. These RockDig ferrules were the same... except that they note in their description that they are mis-labeled, and should be designated as “1/0”. I feel this demonstrates an attention to detail that puts them above their competition.Very pleased with this purchase so far!!

Genuine copper. Sanded off the tin plating to verify. Have been happy with rockdig products so far. Using their terminals as well.

Great product great quality and good value!

Easy to crack them during crimping. The wall thickness should be increased at least 50% to reach a better-quality ferrule.
