The at home appointment was fun and informative with Lee. The install the next day with Lupe went smooth and efficiently, the cleaning promo products are a great bonus!

I had been wanting a home filtration system like this for the sole purpose of not leaving water marks when detailing cars (due to having no calcium in water). I posted some pics as well to show this, I left one spot to dry on its own and no watermarks were visible. I didn't have to fight the Mrs. on this purchase either as she has eczema and realized this would really help her out. She really enjoys the Product as she no longer has any breakouts after a shower.

I scheduled an appointment with Quality Home Products and that's what I got, from the sales associate, Quincy, to the actual product itself. I was already interested in getting a water softener installed in my home, and Quincy was able to explain how the system worked, and answer any questions I had. With the water test, Quincy was able to demonstrate the differences between soft water and hard water, and differentiate between competitors. So, at the end of the science presentation (the water test), I was sold. I'll be reaching out to Quality for other things for my home in the future.
