Query: 1 week planned obsolescence at best!

In college I studied planned obsolescence. It is the practice of marketers taking a product into the market place srictly to make a quick profit based on concept alone knowing full well that the product will not last any length of time and is poorly engineered. In short they knowingly make a cheap product for a quick buck. This product fits the bill to a tee. The profile and weight at the head make it an ahtletic challenge just to hold the brush in reverse to scrub your back. The unit is extremely under powered. Any friction at all needed for proper cleaning and exfoliation stops the rotation. The center lug on my brush broke the first day. I would pay a lot more for a brush that would truly do what this brush pretends to do. This product is a joke as a bath brush but it makes a real good home defense club.
