Customers like the quality of the electronic component terminal. They mention it's well made, holds up great, and the copper rings are very strong. Some say the ends are great for thick wires and that they hold the wire good after a few squeezes.

I think for wiring lower power applications this may be okay.
0 gauge fits in nicely
Probably an easier crimp compared to a copper lug.
They aren't "flimsy" but I don't think their meant for really high current amperage. Might heat up??

I got a bad gut feeling about running these on 6k watts output . I ordered them *like new* but they came dirty. I'm comparing these to copper lugs from sky high. Honestly it's better to spend the extra 8 dollars and get genuine copper or tinned copper lugs and crimp them on. Don't play games with high amperage.
