LifeventureThermal Mug, Leakproof & Vacuum Insulated Reusable Coffee Travel Cup

The flask looks good and keeps your hot drinks hot for hours. Most of the time I use it, I need to take the lid off for several minutes to allow the liquid to cool off a little bit before being able to drink it. It’s size is also very handy as it will fit into almost any cup/bottle holder or pouch. It even fits into cargo trousers pockets!The opening is big enough to make cleaning it very easy. I’ve had mine for a few months now and I know it’s going to last quite some time. I know several people with these and they’ve had them for years and really put them to the test.The only issue I’ve encountered is with the small storage compartment in the lid. A few times liquid from the flask has leaked into this compartment in the lid. The actually flask has never leaked other then into said compartment. So, it is leak proof and won’t ruin your bag or any contents, but the compartment in the lid is basically useless.I would definitely recommend this to anyone wanting an extremely durable flask that is a very convenient size and will actually keep your hot drinks hot for hours. Just don’t use the compartment in the lid for storage if yours does the same as mine.

I have been buying different travel mugs for several years, in the search for a cup that is genuinely leakproof and keeps your drink hot.At last!These mugs are genuinely leakproof (just make sure the little plug is securely in place in the lid, and you don't fill the cup beyond the start of the screw threads at the top). I have never found another brand or style that was really leakproof like these. In fact, they are so tight that you may need to unscrew the top section of the lid to release pressure before you can get the lid off - that's what the extra lid part is for.These cups really keep your drink hot. They are double walled like a flask, and keep your drink hot for hours. You can make a drink at breakfast time, confident in the knowledge that it will still be hot at lunch time. I have occasionally made a cup of tea before bed to drink the next morning, and it was still drinkable, although not blistering hot after seven hours.In terms of temperature, the only problem with these mugs is that they keep your drink too hot! Do be careful if you start drinking soon after making your drink, because it will be absolutely boiling. It won't cool down with the lid on, so leave the lid off a while if you want to enjoy your cuppa.My partner and I now have several of these mugs. If I had to criticise one thing, it is that the inside of the mugs get really badly stained with caffeinated drinks. Within a few weeks, the shiny silver lining will be dark brown, and the screw threads will be stained.I have tried various methods of cleaning the mugs, including denture tablets (they work on plastic mugs but have no effect on these mugs), tough washing up brushes (nope, useless), and steel wool pads (takes a lot of physical labour for little reward). After a few months, the inside of the mugs will be lumpy with dark brown wrongness.In the end, I scraped the insides with a knife to get the worst of the lumps off, then followed up with a steel wool pad, which was effective once the brown coating was no longer intact. It takes probably half an hour of hard graft to get the mugs clean again, which is a pain in the, er, neck.It is easier to accept that the insides of the mugs will be stained and nasty looking, so just don't share your mug with others, or let anyone see inside it, and all will be well. They come in various different colours, so you can tell which mug belongs to each person.Do remember to clean the rubber seals regularly, as they quickly get clogged with caffeine wrongness. Not only does that look grim, but it's probably a perfect spot for nurturing bacteria. Pull the rubber lid seal off and wash it with washing up liquid and, ideally, a washing up brush (to get into the groove), though a sponge will work well enough if you are thorough. Be careful popping out the little central seal - if you drop it and lose it that's the end of the leak proofing. Give the little seal a wipe with a washing up sponge, then leave both seals somewhere safe to dry off.Note that these mugs are cheaper on Amazon than at Go Outdoors, where we first spotted them. Shop around on Amazon, because different colours are, for some reason, different prices. The purple one seems to be the most expensive, but is no better quality than the boring black matt ones (my preferred style).Now that we have found these brilliant mugs, we'll never buy any other kind. They're perfect for commuting to work, taking on holidays (if they are empty you can take them through airport security), and generally around the house - why make one cup of tea when you can make two? Make the second one in your travel mug, and you can enjoy it later without the faff of going back to the kettle. Perfect!

I bought this after a solid recommendation from my wife, who’s had hers for over a year and won’t shut up about it. Fair enough—now that I’ve used it for a few weeks, I can see why.It’s genuinely leakproof. I’ve chucked it in bags, left it rolling around in the car, and it hasn’t spilled a drop. The lid screws on tight and hasn’t shown any signs of wear. The copper finish looks great too—smart but not flashy—and it’s held up well against scuffs so far.It keeps drinks hot for hours. I poured coffee in at 8am and it was still warm enough to drink at 11. That’s plenty for me. Cold drinks stay chilled even longer, which was a nice surprise.The only downside—and it’s a small one—is the sipping experience. There’s no spout or flip-top; you unscrew the lid entirely to drink. That’s fine at a desk, but less ideal when you’re on the move or trying not to pour hot tea down your jumper. It’s a design choice, not a fault, but worth knowing.Otherwise, it’s solid, functional, and feels built to last. Would I buy it again? Yes. Would I recommend it? Already have.
