Описание: Unboxing and Review of the new touchscreen ultra portable and powerfull DSO from DreamSource Lab, the affordable DS4T252 in French.
I'm not a professional "youtuber" (so no stand for the phone, no million dollar camera, no big led ring light, no interior decoration in background), I have only made this video to show you the DSO and its capability for helping people who could be interested in checking this product.
