Title: LID GROWS MOLD
Review: This mug works great the first week. After that, your coffee starts to taste different and a funky smell begins to waft up from the lid when you take a sip. This lid is 1 piece and does NOT come apart like the Thermos Sipp 16oz model. Bacteria and mold begin to grow in the lid area rendering this mug useless and winding up in the garbage. Please beware of this product and choose a model that can be thoroughly cleaned and sanitized.
