    I am new to this site and I’m not sure how to post this question, so I apologize if I am posting in the wrong place.

    Can anyone Tell me how their platinum P300 worked on autos? Been trying to find a non-biased opinion but it is very difficult with the reviews online. Any help would be much appreciated. Thank you in advance

    They have certainly put a lot of effort into designing and building this unit.... too have it fanless is also brilliant....

    Thanks @Dabber figured I'd wait to do review until I saw results. But I could tell upon plugging in that it was going to do what it said.
