Input: Product worked great at first. Batteries do get hot and charge very slowly if charged in phone though. I was able to avoid charging batteries in phone when the charger base worked. Now even dead batteries light up blue when plugged in and won't charge. Requested a replacement from seller still waiting for reply. I will update if issue is resolved with seller
