Review (4/5): Surprisingly effective and easy to use
I've never tried a back scrubber like this before, but I like it! Frankly, it took me a little practice. It is actually good for helping with arm stretches in the shower. (It might be difficult for a very inflexible person to use.) To me, the highlight of this product is that it is easy to clean and dry and would be less susceptible to accumulating bacteria and other such stuff like loofahs and brushes tend to do.
I like the amount of friction with the more coarse side. It is great for skin cleansing and circulation. The one thing I noticed is that soap will accumulate, and so this needs to be rinsed thoroughly after use. For my needs, this is a very useful product!
