They appear to function correctly with the LED LAMP application. The delivery to Greece required three months, but this isn't the seller's responsibility, therefore, a 5-star review.

The uncle accepted the delivery without any physical alteration to it.

The thing is damaged, as if burned, or I don't know the specific cause, but it is non-functional.

The product matches the description. It functions correctly. It uses the LED LAMP application, and not the LOTUS LANTERN application, despite the pictures suggesting otherwise.
