I have the older model tunze wavebox. I've had it almost two years and I bought it used. I purchased a new optical sensor when I bought it. It's worked flawlessly since then. I've upgraded and no longer need it. There is only one magnet on the back but that hasn't affected performance. All it needs is a good vinegar bath and then it's ready to go. Comes with the controller and all cords. I'm not sure I have the manual anymore. $200 shipped. I'd prefer PayPal gifted.
