Query: Terrible product design -- causes scalding and lid to fall out

I tried this product because it was rated so highly by others on this site and was sorely disappointed. During normal operation of pouring hot water from the unit, the lid falls out and steaming hot water comes rushing out. I got scalded a couple of times. This is a terrible product and a lawsuit in the making for this company.
