Off the internet, I ordered a make at home kit to build a device to save 80% on my electic bill. They said it would fit in your pocket and said 100% refund. The item when built is 20 cm. in diameter and they didn’t mention you needed an induction cook top to run the device. | About the refund, they have no refund phone number or no way of contacting Fastspring!! All numbers I called are recorded messages or the people are unavailable.
