I know this sounds weird with the 92 degree weather and all, but my coffee press cozy rocks. It works _really_ well. I am quite pleased with its performance. Before I had the cozy, I frequently would forget my coffee on the counter, or table, or stove top, then find it twelve minutes later and needing to pour it into a cup and re-heated it. I still forget my coffee, but don’t need to re-heat. It’s heavenly.
