Not sure how anything I said led you to say what you did. I don't use night lights. I bought these to replace normal candle use in the evenings and maybe they will work out but my point is that in my experience so far they aren't functioning as they are supposed to - It's that simple.
OK so everything does now seem to be working ok. Charged once and lasted for 24+ hours. Then charged again and this time the charging light did go out when charged. I take back my criticism but at that time things hadn't gone to plan. Product seems good.
