but there's such a great deal on such good

Good deal.

Sound good, Good deal

Good deal.

Work as advertised, great deal for product.

The 2-Pack is a GREAT deal and the quality is excellent

For the price they seem robust and adequate, representing a good deal.

When using this from the preamp to a subwoofer amp and then to the main amp, there is so much hum and noise as to be unusable

Works as you would expect.
