The delivery went perfectly; the packaging is flawless. However, after being put into operation for the second time, the transformer failed. There was a small explosion sound, and it stopped working completely. I checked with another transformer and confirmed that the problem was indeed with the transformer and not with the device. One aspect that should be improved is the inclusion of an adapter for European power outlets.
As for the results, I am still unable to provide an evaluation.
