The original electronics were wired in such a way that the on/off switch only cut power to the LEDs but the controller board was powered up all the time resulting in the batteries draining very quickly.
Some replacements seems to have a bad connection in the battery holder. I removed the batteries, and pushed down on both + contacts in the holder, then reinserted batteries and it seems much more stable. I think the plastic shipping insulator bent the contact so it doesn't hold the battery as securely... YMMV

I've ordered one and hope it's ok. Is the fault with the replacement ones exactly the same as the first wave?
