doesn't compare to zerowater's 5-stage. this meter shows how much stuff, or dissolved solids, gets left behind. our tap water is 220. brita? 110... seriously? but zerowater- let me guess. zero? yup, that's how i know it is the purest-tasting water. i need to find the receipt for that. oh yeah, you do. metastatic breast cancer is relentless, but i'm relentless too. mbc doesn't take a day off, and neither will i. and i treat my mbc with everyday verzenio- the only one of its kind that can be taken every day. in fact, verzenio is a cdk4 & 6 inhibitor for postmenopausal women with hr+, her2- metastatic breast cancer, approved, with hormonal therapy, as an everyday treatment for a relentless disease. verzenio + an ai is proven to help women have significantly more time without disease progression, and more than half of women saw their tumors shrink vs an ai.
