Bests & Worsts Reviews from Amazon

I like the size and glass of this product. However the lid smells awful and ruins the coffee experience every time you take a sip. The fact that the plastic lid retains a horrible smell months after me washing it makes me concerned. Keep cup inspired me because I was trying to be more enviormental concious with my coffee usage but the fact that this plastic smells toxic makes me not inspired to use it and defeats the purpose. I'm concerned for the overall plastic lid and the health effects it will have on me. Something is not right about it.
