The first tuning I was pleasantly surprised that the receiver was also stations, which had my previous somehow "overlooked" (here in particular: Lokalsender OER third parties (eg WDR Bielefeld)). This saw the scan although very good, but I had the zap through the channels find that the tuner is not very strong well. This is also the main reason for the star trigger. Some stations were still jerking sharply on. I had this problem already with a cable box, so I had lying around a signal amplifier through which the problem could be solved. Compared with several receivers, which I had previously in operation, the tuner of C10 suggested but not particularly well. Although I also have to say that our house wiring is not great (hence of old "Receiver experiments" of the signal amplifier in the corner). This could, however, pose some users may be a problem.
From her picture, I must say, I am very satisfied. Just SD channels are represented very well, here I would sorting the C10 in the price range in a leading position. HD pictures look good, but especially in high-priced receivers, the picture is still a little better. For low-cost category, the picture but also fully in order.
A pity I find the sporadic crashes of the box. In the nearly two months my unit is now about four times crashed that only one pulling the plug has helped. Not particularly troublesome, as long as it is not often, but only awarded four stars in conjunction with the weak Tuner stop my argument for this otherwise really good receiver.
I would like to mention the really well-executed time-shift function. Many receivers in low range have this problem. For me the Opticum C10 copes this very useful feature with no problems.
All in all, with one of the top devices in this price segment. Especially with cable receivers you have not a particularly wide range. But what is offered here, the money is worth it. I would buy the unit definitely again.
