Query: Beautiful, but the auto-off is not realiable

This kettle is beautiful. I'd have given it 5 stars if the function was as nice as the looks.However, I have often found that the heat has been on all day long without my knowledge because the "on" light is not very vibrant. On vs. off is blue vs. green and only very slightly lights up. I do not know why it stays on in the first place. It is supposed to auto-shut-off when it reaches boiling.Suggestions to manufacturer:-Make the auto-off foolproof.-change the color of the "on" vs. "off" lights to make it VERY obvious when it is still on.
