I decided to try the starter set of the Scrubbing Bubbles Action Tub & Shower Scrubber after finding it on sale and I had a $1.25 coupon for it. I have to say I really wasn't that impressed with this product. The starter set consists of a flexible foam scrubber handle and a storage tub with four disposable cleaning pads. The scrubbing pads are easily attached to the scrubber handle with Velcro. The white scrubby side needs to be wet to activate the foam. They also recommend you wet the surface to be cleaned before cleaning.
I used this on my tub and shower and while it worked fairly well, it didn't clean the surface completely. We have well water and get a lot of build up from the hard water and iron. I had to use another cleaner to finish the job and the pad did not stand up to the job. I only got about two-thirds of the way done before it started falling apart. The pad is thrown away when you're done cleaning and replacement pads are sold separately. The pad can also be taken off the foam handle and be used by hand to get into tight areas.
I like the convenience of this scrubber, but I would only recommend it for light duty cleaning.
