Excellent industrial-grade wiring that exceeded my expectations. Based on my observations, it's clear that this wire is well-made and durable .Its bare COPPER construction makes it an ideal choice for use in a variety of applications. it was easy to handle and install, and I appreciated that it came in a convenient 25ft length. The only downside was that the packaging was not very sturdy, but the wire itself was undamaged. Overall I highly recommend this product for any industrial and scientific wiring needs..
