It's useful because it keeps water ice-cold for 11 hours and hot for 7 hours without sweating or spilling. It's perfect for anyone who works from home, studies a lot, or lives with a tumbler in hand like me. I love it because it made me drink way more water without even trying and it fits in the car cup holder. I recommend it because the quality is amazing and it's not just hype, it really lasts for years. My experience has been that since I got it I don't leave without it and my desk looks cuter. It's one of those products you think you don't need until you have it.
