Query: The Scummiest Handheld Tool I Own!

I bought the scumbuster a few years ago and have used it several times. I should have returned it. I use no less elbow-grease than I did before and have to continually re-charge batteries. It's easier, faster, and CHEAPER to just use a can of Scrubbing Bubbles and one of those extra-gentle scouring pads. Honestly, this was a waste money!
