This is the device you need to keep the yeast starter moving while you are busy doing something else. This unit has two powerful NdFeB button magnets in the 12 VDC stir motor, which is controlled by a precision voltage regulator for easy speed adjustment. The RPMs of the drive motor are limited, so the motor will not "throw" the stir bar, yet it provides enough to get a good vortex going.

- 110v wall transformer provides power to the unit
- 6" x 4" x 2" tall
