Urgent recommendation: do not buy the DABMAN i560! I had two devices available for intensive testing one after the other and both showed the same errors! The software crashed, the device "hung up" and when it was running, there were always sudden, brief noises. My opinion: A software update would be necessary, but this will certainly not be forthcoming as Telestar has ceased trading. Telestar's business activities. But perhaps there is nothing more to be gained from the hardware? Problems with memory management? It's not Galaxus' fault and they behaved excellently in my service case! Galaxus deserves great praise! And Telestar is not "the bad guy" either, because the Dabman i550 is good, very good. It works to my complete satisfaction.
