Samsung Mm C6

I purchased this unit 1 day, could not receive any DAB channels then received some but lost them again while trying to move the aerial. Finaly took the unit back the next day thinking I was doing something wrong and the engineer said the unit was faulty and he would not have purchased this unit as 50% had been returned as faulty. Pity as it had a great sound in the store and was one of the best looking.
