Poor company policies.

I ordered 2 of these, the first installed ok, the second busted open when I lightly tightened the fastener. I asked for a replacement for the faulty one and I had to pay return shipping. Send me a faulty product AND make me pay return shipping? Won't be doing further business with NVX.

Nice product. A little loud.

It has a pretty loud click when you turn the key over. But it’s better than the oem 30 amp unit. I am using my aux battery to power my 1600 watt sound system p=Vi or 1600=14.4i or 1600/14.4=111amps

Much better quality over another popular brand that was more expensive. Very pleased with the product.
