Bad Quality Product.

I bought the JBL Horizon through The Brand Store (www.thebrandstore.co.za). The first unit I received gained time - about 10-minutes in a week. They then swapped out the unit for me and it seems to be working well until recently when it started gaining time again. I give up... This is supposedly a premium product, especially given the premium price. The clock on my stove is keeping better time than this product. Never buy JBL again!!!
