Ease of use and perfect terminations with the right crimping tool.
This item was outstanding. I was concerned buying it but so very pleasantly surprised. I used it with 2/0 welding cable (pure copper) for high-current terminations. These lugs went over the stranded copper with ease, and crimped perfectly. I highly recommend this product.

Functional, Great price!
Works well but my sleeves didn’t form well with heat. Otherwise, I would have given a 5-star. Great price though!

I’m pretty happy with these
I looked at the auto parts store and they wanted $6 a piece for these. They were slightly heavier than these and probably better but I don’t see why these would not last a long time. They are not flimsy. Heat shrink seemed good and I crimped them on nice with a hydraulic crimper

Good Quality
Good quality, good fit. I was able to bend tab of one 90 degrees (used a hammer and vise) with no signs of stress after crimping to come straight off the side of a contactor.
