Title: Would love it except for the uncleanable lid
Review: MOLD. The contigo mug has been washed repeatedly in very hot soapy water, but can't get rid of the mold inside the lid. The water seems to have become trapped inside the lid so it doesn't dry properly, even though I do dry it opening down. If it wasn't for this, it would be a great mug, but the growth inside is absolutely disgusting and probably horrible for you. Regretfully, I'm throwing it out. Didn't buy it from amazon (Costco) but wanted to warn people of this downside.
