Review on ADOVEL Substances Showerhead Replaceable Cartridge by Maurice Strawther

I really liked this shower head at first - it's big and has great water pressure. However, I have never been able to tell if it serves the purpose I bought it for: to soften and purify water. There was no improvement in my hair and nails as others have said. Then, a few days ago, while washing my hair, I heard an audible "click!". Since I've been using it over the following days, the water has gotten worse, ie it's splashing everywhere. My husband looked at it and said it couldn't be fixed; he needs a replacement. I really hope I can get a free replacement from the company.
