“Oh well! How do say that. I have couple of tumblers/ thermo mugs with large capacity. But this is winner. From moment I took it use, it has been near me at my living room soma table. So, I easily consume at least 2 liters of water daily. That is so easy to use. Fill it at morning and enjoy during day. I use fridge cold water with Microdrink cubes and water inside Thermo stays cool enough until it ends.”
