This Shungite Bucky Bandaid Sticker should be used for electrical devices that don't transmit a signal. Electrical signals produced by any electrical device (stove, washer, dryer, dishwasher, lawn mower, blender, hair dryer) are attenuated by the Bucky Bandaid. For electronic devices (devices that communicate/transmit signals) see the Shungite S4 Sticker.
*This DOES NOT make a microwave oven safe if a Shungite Bucky Bandaid Sticker is used, the best option is to not use a microwave oven. If you do need to use one the next best option is to have a Shungite Bucky Bandaid Sticker placed on it.
