The point that a lot of these YouTubers are making is that DKOldies claim they clean and/or refurbish the consoles which justifies their 3X cost price compared to rivals and the general market, yet in many cases including normal customers, there is huge evidence that they do not always do this and in some, the machines are internally damaged on top. They make all these TikTok's showing the utmost care and attention to these alleged orders yet what people receive and the way it's delivered is literally taking the piss.
YouTuber's can burn money on things like this for videos but if you were a normal person that spent $450 on a classic Xbox that was delivered in a bashed up box with the console protected by bog roll and the machine wasn't cleaned or even tested, then you'd feel very hard done by, bordering on scammed. There's not many places you can buy machines safely, especially with places that offer a comprehensive 'specialist' service and guarantee so when they start half-arsing it or not doing things by their book and charging triple, it's kinda sad.
