    Leaks, there­fore not fit for pur­pose. Dis­ap­point­ed.Have updat­ed to 2 stars as the sell­er was help­ful in pro­cess­ing a refund. Prod­uct still not fit for pur­pose but I do appre­ci­ate that they were so help­ful in sort­ing it out.I thought it worked okay, but was mak­ing con­scious effort to keep it upright for a while as I was hes­i­tant to trust it.Today I put down my bag which I had put it into and trust­ed and when I put it down on the bed, I left it for maybe five min­utes and then went into my bag and my hand was wet. Every­thing was soaked and it soaked through onto the bed and through the duvet to the mat­tress. I don’t even know exact­ly where it leaked from, but every­thing was closed and locked. And the whole thing was wet amongst every­thing else.Would not rec­om­mend and now I’ll be on a search for anoth­er option that can actu­al­ly keep the liq­uid inside the container.

  2. Ama­zon Customer

    Opens too eas­i­ly, not safe.It’s styl­ish, nice wide neck for clean­ing, and easy to hold.How ever it pops open too eas­i­ly, it opened in my ruck­sack cov­er­ing all my clothes and doc­u­ments in black coffee.

    Does­n’t keep drink warm for 6 hoursThe flask is well made but does­n’t keep drink warm for 6 hours + best you will get is about 2 hours and the flask gets real­ly warm so not good ther­mal­ly and not good to hold

    very nice designI love the Design

    Keeps hot for hoursBril­liant flasks, keeps my tea hot for hours I usu­al­ly have to leave lid open so the liq­uid can cool down so I I can drink it !Would high­ly recommend

    Super prod­uct.This is a real­ly good prod­uct, quite unusu­al. I’m sure there may be oth­er sim­i­lar around, but I haven’t seen before. It is a cross between a tra­di­tion­al vac­u­um flask and trav­el mug, giv­ing the best of both worlds.Quality is excep­tion­al­ly good, the real test of it’s effi­cien­cy being whether the out­side remains cool to touch when filled with tea / cof­fee etc. This does. You can’t even dis­cern even a hint of warmth. There­fore it keeps drinks HOT! I’ve nev­er tried a flask (let alone trav­el mug) that keeps bev­er­ages as hot as this one does. It’s incred­i­bly good.This is real­ly easy to use, sim­ply press the but­ton, and the top opens, expos­ing the drink­ing spout. It real­ly is superb. Capac­i­ty is equiv­a­lent to a very large mug (450ml), so enough for a jour­ney, or for sharing.In being whol­ly objec­tive, as I always am with reviews, I will look for neg­a­tives as well as pos­i­tives. Inso­far as per­for­mance, I can­not fault this. Prac­ti­cal­i­ty wise, I would have liked the exte­ri­or to be at least tex­tured for a more com­fort­able grip, and a car­ry-strap would have been nice too. I do also sus­pect the exte­ri­or fin­ish may scratch if in con­tact with say, keys etc. There is noth­ing that makes me think it will, just sus­pect pos­si­bly. This wouldn’t affect the prod­uct effi­ca­cy though. Unlike a nor­mal trav­el mug, this is total­ly leak-proof. TOTALLY!Overall, if you try this, you’ll like­ly nev­er go back to a tra­di­tion­al trav­el mug, it’s that good. First rate qual­i­ty, real­ly good val­ue. High­ly recommended.

    Keeps hot drink hot for sev­er­al hoursI have a trav­el mug with a flap top, but I want­ed a flask which I could put in my bag and not wor­ry about leak­age. So when this stain­less Insu­lat­ed and leakproof flask 450ML was offered on Vine I ordered it straight away.I filled it to about 2/3rds with hot water to warm the flask up before use… but I com­plete­ly for­got to make a cup of tea and left home with­out it. After 5 hours I returned home and checked the water, and it was still very warm. Bear in mind this water was added to warm the flask up rather than for drink­ing. So I was pleas­ant­ly sur­prised how long it kept the temperature.The lid flip open ful­ly so you don’t need to wor­ry about your nose touch­ing it. It’s easy to drink and clos­ing is just as sim­ple as push­ing the lid back on.Highly rec­om­mend it.** a cou­ple of things I’d like to add: — when you put hot water in it, don’t close the lid straight away: when water cools, the air con­tracts and pre­vents the lid from open­ing — if you use this flask in you car, don’t try to open the lid while you’re dri­ving: for the above rea­son, the lid may not pop open and you might get dis­truct­ed by try­ing to open it which is dan­ger­ous! — try and shake the flask and see if the air inside expands again — if the water is still hot and the air expands again you should be able to open the lid.

    Fab­u­lous drink­ing mug!This fab­u­lous drink­ing mug has a 450ml capac­i­ty, which is great for tak­ing out with you con­tain­ing a hot drink and for fill­ing up dur­ing the day. On receipt sim­ply remove the cap and fill with boil­ing water, leave for about fif­teen min­utes and then pour out- this will remove any last­ing odour from man­u­fac­tur­ing and pre­pare it for use. Most cof­fee shops these days will give you a dis­count for pro­vid­ing your own cup, and this has a flip up that reveals a wide sip­ping area. Remem­ber that if you are using a hot drink, not to gulp it down as you may scald your mouth, because this is an excel­lent heat stor­ing device. Per­son­al­ly I find that if I am to fill this at break­fast it is still pip­ing hot at lunchtime (5 hours lat­er) and the same goes in reverse if I am using it for a chilled drink. For a test, a chilled drink seemed to last 8 hours with­out notice­ably warm­ing. The fin­ish on this is bril­liant, allow­ing me to use this with­out wor­ry­ing too much about marks and dam­age. I chose the blue which is more like an Aqua or Teal than Blue, but what­ev­er you want to call it, it is magnificent.I real­ly love this drink­ing cup and can rec­om­mend it with­out hesitation.

    Smooth sim­plis­tic and awe­some flaskThis is a 450ml flask for hot or cold drinks and it is one beau­ti­ful­ly craft­ed flask with its sim­plis­tic looks.I like its plain look but yet feels lux­u­ri­ous and nice to hold that paint­ed cold steel touch.The but­ton unlocks by slid­ing it up and then press­ing it to release the spring loaded cap. The cap is made from durable ABS plas­tics and can with­stand impacts.I could drink from the con­toured curve which has a dip in it. This means If I had hot cof­fee, I could pour enough to fill the dip and allow it to cool a lit­tle before drink­ing it. The lid has a good sil­i­cone seal plunger which plugs over the hole.The cap screws nice­ly onto the flask positively.The flask kept my hot drinks hot for around 6 hours and plen­ty enough as I top up anoth­er coffee.I like using this flask which holds just enough for my liking.The flask is also easy to clean.I think this flask is excel­lent value.

    Handy size and well priced: no secur­ing clip on the “open” but­ton.I received this item through the Ama­zon Vine programme.This is rather a smart look­ing ther­mal bot­tle, I ordered the plain black one and I do like the colour and finish.Handy size at 450ml for sin­gle hot drinks, you don’t always want some­thing of a litre capacity.Seems to work keep­ing my cof­fee hot, I’ve only tried it over around 4 hours but it’s worked well enough.Doesn’t leak, though the only crit­i­cism I would make is that the top/spout is secured by a push-but­ton and does­n’t have the addi­tion­al secu­ri­ty ring/clip stan­dard on these sort of bot­tles. The­o­ret­i­cal­ly the but­ton could be knocked “open” and the con­tents spill into your bag or wher­ev­er: not very like­ly I admit, but I was sur­prised to see no lock­ing feature.Reasonably priced at £11.99.
