I make up a batch every two days. I so much prefer cold brewed coffee i have not had a hot coffee (at home) since the day after getting it. The only issue (and it's a big one), is that the rubber seal works while the coffee is steeping but the lid seals well when brewing but clunks and wobbles (metal on glass) when the strainer is removed. The rubber is on the strainer top not the lid. Would I buy again? Yes, if they fixed the sealing issue. No if they didn't.
