The state-of-the-art Powerball that my vacuum cleaner was never went underappreciated. It was my faithful companion for over a decade and a half-- with not a cough, not a hiccup to berate it for. I named her Allegri, and it did what her maker promised it’d do for me-- I saw a massive change in my son's health, gave me peace of mind, and saved me money on medical bills. Tell me, wouldn't you be grateful for something like this?
