Its been the worst overpriced investment I've made.
If you don't mind being way over charged for the the water softener product that other vendors sell then less than half the price of VER but do the same, then VER is for you. Be Aware that after 5yrs of use, this crapsystem began issuing a gray to black water that is considered not harmful and perfectly fine according to them, and you thought "the fogy water looked bad!" So if the chlorine is high in your area it will dissolve the coal in your filter tank causing the water to come out black and staining everything from toilets, sinks, tubs, and clothes, even the pool.
VER recommended dishining out another $700 to have tank replaced , haha...
And can't guarantee it won't continue to occur.
Paying the system, and for salt bags and services, I have easily exceeded $8000. You've been Warned
