Yeah, that's been mentioned by the (mediocre and shady) YouTube reviewer TechmanZ.
What's so shady about TechmanZ, haha? He's better than a lot of others out there, buys mostly everything he reviews (for those that care) and is about as straightforward as it gets. Mind you he could spend more time with something before reviewing it, though we're not really his target audience so I doubt his main audience would care.
