Update*Seller offered a full refund and to replace unit. Increased rating to reflect the customer service and seller. I have not used the product yet.The heater looks badly damaged upon arrival. Plug is a 220V not a 110V, you would need a converter to use it. Really disappointed at this product, since it is the most affordable kit to start steam distillation. The heater is also just a electronic stove top heater, may be easier to purchase one yourself more reliable!
