I just bought this micro-tuner so you can watch tv from my smartphone Samsung Galaxy S2 without using my internet package. I was very disappointed with the poor quality of the tuner, which captures no chain with the small antenna from my home located in peri-urban areas (12km south of Lyon). The use of the wire antenna is indispensable, and again, the tv is very jerky. I think this product is truly valuable for use in the city center, close to relay antennas.
