This is the 100 piece set of 8, 6. 4 an3 2 Ga copper lugs
This is the second set of these lugs I've purchased. I've built quite a few cables using these lugs and they have worked well for my purposes. They are bare copper and come with what seems to be a good quality heat shrink. If I were to build a larger system I would likely want to use plated lugs that are thicker material. These lugs are somewhat light weight for a serious load but I give them 5 stars because what you get for the price is completely acceptable.

Great Lugs
I installed a solar/battery/inverter upgrade in my RV. I ordered quality 2AWG copper cables with 3/8" lugs, since this was the largest size I would need. The system worked but I was disappointed that I could only get about 1300 watts out of the 2000 watt inverter before it would trip. I had researched that inverter tripping was most likely due to either undersized cables or improper lug size. It was the lugs that were getting me, Breakers have 1/4" studs and my batteries had 5/16" and the monitoring shunt required 3/8". Once everything was cut to length and properly lugged my inverter easily sustains its rating. These lugs do a nice job and can handle the high current demand. The heatshrink included seems to be of very good quality. Good value for the money.

Good range of sizes. Professional quality
we use these to repair automotive battery cables. They seem to be good quality. The heat shrink is 3x ratio or better and has the glue inside. Using a hydraulic crimper makes for a clean professional repair.

Great assortment. Shrink wrap works nice. Shiny
These all look nice, afaik, they're all shiny copper and no sharp edges, burrs, or defects. They crimp down nicely. The shrink wrap color-coded sleeves are nice, and shrink nicely, and appear thick and evenly shrunk down. I think there's adhesive, or maybe not, but the seal looks great and not going anywhere. I probably don't need to, but I sometimes will double shrink-wrap it. Satisfied.

Quality lugs
These are quality lugs that meet specifications. They are correctly dimensioned, and you can tell they are made out of good quality copper. The heat shrink tubing also has some sort of heat activated glue which is nice.

Pure thick copper and very nice heat shrinks. Same quality as a local electrical/electronic hardware store, but with a greater selection and better price.

I used these lugs on a 24V solar power project for my off-grid workshop. They're great value for the money, good quality metal that crimps well. My only issue is the shrink wrap isn't great... it's rigid and larger than it needs to be, I had trouble getting a good seal on the 8AWG lugs. On the smaller lugs I used other shrink wrap I had lying around. But overall, this is good quality lugs and a great price.
