About 3 years ago, we ran across this product in the grocery store, and it looked interesting, so we purchased it. We live in an old-fashioned Los Angeles apartment that has a separate tub and shower, and the shower is about 2-1/2' x 2-3/4'. It is awkward to clean. So we tried this out, and fell in love. It is PERFECT. I use it about once or twice a week, and it keeps the shower extremely clean. The first one we bought broke down a bit too soon, so we contacted the company and they sent a replacement. Just recently, that one finally wore out (they are equipment after all), and our closest grocery store was not currently carrying it, so we checked Amazon. To our delight, Amazon had it, and at a reasonable price. (We were already buying all our refills here by the case, and will continue to do so.) This is a fantastic item to own, especially for small showers. You can't go wrong by at least trying it. We will NEVER stop using it.
