Purchased around January 2025 and used for about two months. I switched to using water from a water server for making milk soon after, so I put it away for storage. This product was a real lifesaver during the period when I was frequently making milk. I also used it for making tea during that time. I regularly cleaned it with citric acid, but there is some water scale on the bottom.
