I use this every day during my commute to work and it’s the only travel mug that actually doesn’t leak even if it’s in my bag and keeps the tea hot for hours. I pour the water in at 6am and it’s ready to drink at 11. It’s phenomenal

It's pretty good in winter time. Only 2 left when purchased so did not have good selection of colour. It does what it says, keep the water/ coffee hot in pretty much 5h. Have not tried cold water. The handle is easy to carry around. Not suitable for driving as can't slide lid open with 1 hand. Not very easy to clean lid if used for coffee. Overall I am happy with the size, the handle and Thermos is a reliable brand as I have couple of products from them at home for years.

Unfortunately I had to return this mug after 1 day of use, the locking feature is a separate part and it kept detaching and falling to the bottom of the mug. You can take this part off but this locking feature stops the drink from leaking, I tested it out and without it upside it’s like there is no seal, my drink came flooding out. It’s such a nice mug, I bought it because of its beautiful brown and its functionality. I instead bought a yeti

I don't know how I managed without this! The handle is perfect for carrying on my walks while juggling the dog etc.. keeps hot 🔥 with cool exterior. Mechanism in the lid needs a bit of expertise but once you know how to make it seal its leak proof!! Very happy 😊
Great thermos if you like your jumbo lattes! I make a jumbo chai latte for breakfast and it lasts me through to morning tea. Keeps my cuppa at the perfect drinking temperature for hours.
I love the shape and the design of this travel mug and find it quite easy to fit in my car's cup holder, the pram's cup holder too! And it does it's job so well by keeping my coffee hot just the way I want it to be especially with little ones your coffee is always going cold! But not anymore! M so glad i bought this finally! 😁
Beautiful insulated travel mug, love the colour and design. I have smaller hands so it's slightly more difficult to hold, but it's a small downside to deal with, as I prefer the larger size mug.
Lovely colour and good size. However that’s where the good review points end. The first time I used it, as soon as the cup tipped even slightly it dropped a reasonable quantity of hot liquid in my bag. I returned it to the store. Not good enough. Never had one of these leak before and this is supposed to be the ‘best’ brand. This should be leak proof. Noticed leaflet inside cup stated it is not leak proof or dishwasher safe. Would not buy this again.
Wifey loves it! She uses it everyday at work! Need to ensure the locking mechanism is in place under the lid to prevent spillage. Great travel mug.
Lid has warped after sterilising It is impossible to clean. It warped to much that it has r3ndered the cup useless. I will contact the company also as wish for a refund. Disappointed in the design regarding health and safety.
