I haven't tried it yet. To be a product Delicate came only with the packing bag and the box was shattered, but the device was undamaged. When I test it, I'll comment again.
Box arrived with a lot of dents but the product is working fine. But on a review on the product itself everything is good except the power adapter, it becomes very very hot 61c . But the cup base is excellent and it reaches 0c (see attached picture).
Power cable faulty and refunded part of the cost
