This is probably the most user friendly noise eliminator. Its a super simple, plug and play unit where you just plug it into any outlet that your hifi system is sharing with and you are good to go. When you see the blue light (it will blink intermittently) come on, you know the unit is doing its job as it harvest the noise and discharge it out as light. Simple but wonderfully effective.
Unit looks good with minor scuff marks here and there common with use. It will be securely packed for safe shipping.
