The product was received sealed, but the packaging did not look factory-made. The box was wrapped with simple cellophane on the outside and not with the authentic factory wrapping, which raises an initial reservation. Also, there was a slight burnt smell upon opening.
Nevertheless, I did not want to be biased, so I tried it as normal. So far, after 2 months of use, it works properly and in terms of performance I am satisfied.
However, in the space where I have placed it, even though there is constant music, the fan operates almost continuously and its noise is noticeable, which concerns me.

Very good, used in a 12V oil burner where a lot of Amps are needed for starting and I had no issues. Also, the fan speed varies according to demand.
