Review: High quality and value for money - Tinned nicely. Feels high quality, like more famous brands. This brand comes in more convenient sizing for shorter runs in sprinter vans. They, of course, will sell bulk sizes too. They ship fast from their distribution center.
Review: Heavy Duty Power Cable - While the cable is stiff, there are lots of strands in the individual wires and it is about as flexible as can be expected. It should give me many years of reliable service.

### ⭐⭐⭐⭐ Stiff insulation, but otherwise great product.
*by S***G on April 6, 2025*

The insulation on the wire is very stiff. It is hard to wire in my RV AC/DC electrical panel.
