I received this item as a birthday present and was excited to use it. I read the direction (which were vague)and then filled the unit with water halfway between the min and max. It ran for 5 mins and then gave me an Err....not enough water although it was well above the min line. So I filled it to the max line and again after 5 mins it gave me the Err. How disappointing.I looked at the review to determine if this was common and found out this item contains BPA!!! BPA + HOT water is not a good thing. Extremely disappointed in Oster for putting an item like this on the market.
