We ordered a "Sonic Scrubber" and so far so good. But to order it I had to wade through about a dozen "add-ons" and special offers, etc. Which all look good but would triple your price.
Years ago I ordered a Merle Haggard cassette from a commercial - forgot I had done it until it showed up C.O.D. - the things that sound like a good idea at 3AM, LOL.
