Electronics defective, charging slot display spins

Video on Amazon.com Watch Now it was time that lying around and emptied accus re-load again, to make them fit lamps for my mountain bike. But what is, nothing works. Bought on 2 December 2013, just six or seven times in use, and now broken ?! Is not it yet.

The error:
The display will flash when you connect the supplied power adapter cord briefly, indicating different values. Initially (slot 1: 88, Slot 2: 87, Slot 3: - Slot 4: 35) and now only (slot 1: 42, Slot 2: 42, Slot 3: - Slot 4: 35) to each well for at -sec. It is then followed the complete display (all display values) in the functional test. Then appears on each charging bay the famous "zero" as it should be if there are no accus in a loading bay. About the "Mode" button, lets off and adjust to something about the used accus now load. But none that display now returns to the flashing display values ​​already described when I try to set the charging current.

If the electronics are defective? I dont know. Given the minimum and regulatory use of the charger, you can surely expect a longer lifetime, than my Accu charger. I am really disappointed and will now exchange the device from Amazon.

Note:
Even as an indication of potential new customers. The charging cable is 100cm long, extremely rigid and unwieldy! I find that very poorly dissolved in the handling, as you never know how and where to lay the cable long, since it is so stiff and only disturbs. Here also cable breaks are possible in a short time. Would not surprise me anyway. If this unit does not this defect and would the power supply cable not be so unwieldy that I could give the device three stars out of five, also in view of the asking price. So it is but only one star out of five, and I speak not endorse a purchase from.
