The concept is simple and the construction even easier.
Place the holder using the suction cups on a surface such as a mirror. Next, squeeze your toothpaste through the hole at the bottom of the holder. Put the cap over the device and you are good to go.
I apply pressure to the lever controlling the amount of toothpaste released. It seems to work; however, it does take a few seconds. Also, the volume of paste on the brush leaves a bit to be desired.
But one of the best parts about Touch N Brush, it's easy to pack up and take to to the office.
