Its just ok. I have a Klipsch the One, and I would say its slightly worse than that. So I guess it just depends on how much you paid. I paid, $58 with tax and shipping from Amazon, so I think its worth $60. BUT, I would have been said if I paid full price. Full disclosure, I've had a lot of Klipsch and other decent audio over the years so I'm a slight snob. That said, again for the money, it has a mic and battery (battery means its consumable trash) but makes for easy portable set up, its fine.

Solid choice for fuse holder

Size: 300A Fuse Holder

It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
