I read prior to my purchasing the Krikiken other and made a decision. Of the many positive opinions I am by my very practical experience of this product convinced and enthusiastic. I hope that long-term use reinforces this impression. From my perspective, I can recommend this product highly. After a normal operation of the unit for 4 months, problems occurred with the hard disk. The recorded movies / concerts were shown and could not start. The next day all the shots were gone and the hard drive yet indicated stored data. Another day were these no longer exist. A phone call to the manufacturer, whose phone number is no longer switched to the service booklet, that had to be researched, revealed that the hard drive is defective. So device Back to Amazon: as simple as plugging withdrawal, but not to get the device at the same price. Because I thought that maybe it's a Monday mistake and I stand by my previous companies estimate otherwise, I have just ordered the same but more expensive model. New device, new luck - I thought at least. After only 14 days, the same error image. Suddenly all stored movies away, even though the hard drive still shows data. Again call the manufacturer and have to be aware there, I should do a software update. Since selling the devices (wahrscheinkich) faulty software !!! Well, downloaded new software recorded and made test shots. Since the part has recorded only Filmlaengen 2-3 minutes or there were no previous recordings on it, even though the device was switched on and a recording operation is displayed. I'm now really tired of this product. My recommendation to buy from the top, I can not maintain the best of intentions. On the contrary, I warn all before this scrap !!!!
