## Customer Reviews

### ⭐⭐⭐⭐⭐ Sturdy solid cable lugs for solar battery cable wires
*by D***C on May 25, 2025*

I am very pleased with these lugs. They are heavy duty solid lugs and work well with the battery cables that I make for my solar battery bank.

### ⭐⭐⭐⭐⭐ Best for a good fit on heavy duty cable
*by C***S on May 19, 2025*

Works best for the crimp tools sold here on Amazon. The 6 ga lugs included with the crimper were light weight and could not hold the cable. These worked as they should with the crimper.

### ⭐⭐⭐⭐⭐ Great quality for marine environment
*by S***N on April 19, 2025*

I've used a few of these now, in rewiring my "House" and "Starter" battery banks on my boat, using these 6AWG lugs on the charger connections coming from my 2 Victron IP22 chargers, and I've been surprised how good they are, solid, same ~7-8 grams tinned copper weight as my U.S.-made lugs, very nice, uniform tinned coating.....and, just noticed on the bag today, after crimping a few more, that they're not Chinese...they're made in India....a sign of the times ? I'll buy more, if I run out of this bag of 25.
