Title: Tastes like plastic
Review: I bought this mug to replace a similar item that had stopped heating. The new mug looks the same on the outside, but the interior is plastic rather than stainless steel. The visible plastic rim should have tipped me off, but I wouldn't have thought it could turn out this bad. It heats up just fine, but when it does, my coffee tastes more like plastic than like coffee. I tried washing it a couple times and heating up some soapy water in it, but the plastic taste remains. Keep searching until you find a heated mug that you can confirm has a non-plastic interior.
