Title: Looks Great, But It's Not Effective at Retaining Heat
Review: Although this lid is made from a nice piece of glass, I found it ineffective at retaining heat with my six-cup Chemex pot. Previously I used an old insulated French press pot to keep my coffee warm. That was a much better solution. With this lid, my coffee became lukewarm after fifteen minutes. Too much heat escapes from the pouring groove of the Chemex pot. I was hoping for one less thing to wash every day, but this was mostly disappointing.
