Meanwhile, the second "Kobil TAN Optimus" (Sparkasse Edition) is more or less failed with me, ie: Report Both devices, more or less regularly "batteries almost empty" At first I did it then also renewed, but the problem is with device , Meanwhile, I know this and ignore the display easy. Unfortunately, now no longer works for both devices, eventually the instrument reports "empty" and refuses to work even at 3.2 volts, depending on the button cells. If you herumprobiert something comes back out a TAN. A complaint at Kobil ended with a rejection.
Mir reichts, I just got a Rainer SCT ordered me, let's see if I will soon have to continue around annoyed.
