As others have noted, the lack of connection instructions will make it difficult if there is no relevant knowledge.
Otherwise, it has very good functionality and a nice appearance.

I bought this specific product and to my surprise, I found a complete absence of connection instructions. Neither on the representative's website was there anything relevant besides an icon, nor on the Greek internet, only some videos that mainly present 12-volt buttons. So if you don't have deep knowledge of an electrician, prefer something else {e.g., with two or four pins}
