The Conair infinity pro spin brush is an electric hair brush. It has a variable speed rotating brush head run by an electric motor. The brush head can expel both warm and cool air through holes in its surface. This brush can be identified by its cylindrical rotating brush head and the serial number BC178RBCR. We have found that the main problems with this device are with the fan motor, the brush head, and circuit board. we intend to make repair guides for these three issues.
