Review (5/5): I got one and then my wife did too
The Extra Long Silicone Back Scrubber, Joyvio 31.5'' Silicone Shower Towel is a new type of scrubber that I really like. The scrubber makes it much easier to scrub your back and other hard to reach areas.
There are two handles and the surfaces are different on each side of the scrubber for varying effects. I've found that the side with the bumps works best for me but it's really a matter of personal preference.
The scrubber is long at 31.5 inches but some big people or people with mobility issues might have some difficulty using this like any other product. Be realistic when making your selection and when setting your expectations and you won't be disappointed. This isn't going to change your life but it's a decent way to scrub your back.
