This device makes dehorning easy. Place it over the horn and rotate it to apply heat evenly around the base of the horn. In 4 to 6 weeks, the horn button will drop off, leaving a smooth, well-healed area. No loss of blood or severe shock during or after dehorning. Only a few seconds are required for the entire operation and it can be done safely any month of the year. Operates on 110 volts, AC or DC.
