This equipment has been claimed by me three times. Duration 6 - 12 hours then the unit is the ghost. After the third complaint, I asked for a credit. This was not granted me. I have now been sent the same 2 units, one of which is broken by a running time of 5 hours. This 4th Reklamtion I send back to the Reparturwerkstätte. According tel. Consultation with the workshop (and Philips) I can with a sending up to 100 times reckon I'm tired, continue to join this time and trouble. Who made the same experience?
