I dont have an odor issue, an adode issue. Wanted to wait until i new for sure this product was worth the hype. When i isnstalled it last feb it showed 2.3 volts going to the andoe it was 2.1 volts a month later and is now at 2.7 volts. The green light stays lit and i dont any issues. i flushed it last week and the water was clear. Like the product.
