"Drinks not staying warm!" star star star_border star_border star_border I like the design of the cup and lid but it doesn't keep my coffee warm for very long at all. I've had other cups which keep my drink warmer for longer and this is disappointing. Mrs Kirk - 10 February 2021 support_agent A note from the team Thank you for your review. The cup is designed to keep warm for up to 90 minutes but we’re sorry this hasn’t worked as well as you hoped. We’ve been in touch to offer a full refund.
