Cup is very delightful looking and is a good design, however disappointing with the time frame of staying hot. Don't seem to keep a tea hot for longer than 2-3 hours!

Not really worth all the hipe if I'm honest

Lovely travel mug, although a bit smaller than anticipated. Bought for a present so can't vouch for how long it keeps drinks hot/cold yet!

Great design — a pleasure to drink from, noticeably lighter than other flasks, totally leakproof and really keeps the heat.

Excellent product and is great for keeping your coffee hot and yes it doesn't leak.
Would highly recommend.
