Thermos flask
Brilliant flask and kept my drink ice cold the whole day. After over 6 hours I still had ice in my drink.

Nice Temp readout on lid with neoprene carry case.
Liked the temp readout, carry case, choice of colours since first release (Black or Red only) and will fit in a bottle cage on a road or mountain bike without the neoprene cover. Disliked that the price had increased since bought 1st generation black one for my daughter that was cheaper and included a bottle brush for cleaning; battery for the temperature readout is not replaceable but vendor will sell you an expensive replacement lid when your battery expires in 2 years or so. For the first month worked very well with cold liquids (haven't tried with hot yet) but since the start of Nov. 2020 the cold water comes up to room temp in 4 - 6 hours rather than staying cold for the advertised length of time and no I haven't dropped or abused the bottle which being stainless steel should be quite robust. I also have a similar Tru Bamboo dual wall steel thermo bottle with a bamboo outer skin, this HAS been dropped (rolled out of the estate car tailgate) that dented the lid and scratched the bamboo skin however this still keeps liquids hot and cold for up to 8 hours or a bit longer.

Simple, cool looking large travel mug
This travel mug arrived safely packaged encased in protective film in a cardboard box, the box itself was plain and perfectly suitable to give as a gift. The travel mug also comes with a neoprene sleeve with and fabric loop which I use for additional insulation but I imagine would be handy for a hike or exercise. The travel mug itself is fairly simple, no branding, a simple screw top and a touch sensitive temperature display on the lid. The size is perfect for a large drink, and it fits perfectly in all the car cup holders it’s been used so far (Mercedes, Volvo, Nissan and Saab) not being too slim as to wobble in the recess, although It being tall; it may topple over if the cup holder is shallow. The screw lid is tight and hasn’t leaked when laying horizontal. It is easy to clean with the only area somewhat problem being the inside of the lid where there is a 1.5mm wide 20mm deep recess around the inner seal which has become stained. I have used the mug over a dozen times so far (albeit not every day) and the display is still working and clear, the black finish has not chipped away in an areas and minor scratches don’t show up too much. The temperature appears to be accurate and is useful when storing hot drinks for long periods- a black coffee lost less than 10°c in a 4 hour period. The main issue I have with the travel mug is that the display is hard to read even in very indirect sunlight, and impossible to see in bright daylight however I mainly use it in the car and so rarely have a problem with this. Overall I would recommend this travel mug, it is solidly built and has a simple clean aesthetic, the temperature gauge is a bonus.

Completely Useless
I bought this bottle last year and it was absolutely wonderful, I loved the sleek design and the temperature measurement and it kept my drinks cold/hot for the whole day. Unfortunately I lost it after a couple months so I decided to buy a new one October 2019, and where do I start? The battery ran out about 2 months ago, despite saying in the description it lasts 2 years it got nowhere close! The plastic bottom of the bottle has broken off and has a crack in it. It also leaks all the time, I've checked the tightness of the lid and it's so stuck on so I have no idea how it still leaks! I'm upset about this because it was a great bottle but it's just terrible now and i'll have to throw it away.

Fantastic Thermal Flask
I bought this after a recommendation from another Mum to go with my Nuby Rapidcool as the flask I got with it is not great at keeping the water hot. This flask is amazing and I take hot water out with me everytime I go out just in case. The handy temperature display is useful to keep track of the temperature inside the bottle during the day. When using this with the Nuby Rapidcool, I am able to make a bottle up within minutes (for a new, first time parent this has been a godsend!) If you are looking for a gift for someone who is soon to become a parent this would be perfect to help them with formula feeds!

Good flask
This flask is great. Keeps water really hot for a long time. I formula feed and it’s great having boiling hot water next to the bed for nighttime feeds and not have to get up to boil the kettle. I take a full flask of boiled water up with us and it stays hot for hours! The NHS recommend it has to be over 70degrees and the bottle with the temperature touch lid is so handy to make sure it’s over 70 to use in the formula

Faulty flask?
Unsure if I have received a faulty flask. The flask worked perfectly and was the perfect pair to my nuby rapid cool. However, after a few weeks it stopped working and wasn’t keeping the boiled water hot for as long as when first purchased. Disappointed because I loved it! Emailed for a replacement hoping it’s just a one off.

Amazing Flask
I think this is a great product. I purchased it as I accidentally dropped my Costa Flask when I was closing the office. I've had the product around about a week and it's the best flask I ever have had. The temperature of my Tea was piping hot three hours after pouring, traveling to work and taking sips every now and then in traffic or at work. I highly recommend, I haven't used it for cold drinks yet but I plan to when at the gym. The flask is a great design and really cool, plus it comes with a sleeve to make it easier to hold. Finally, the temperature is displayed on the lid which is a really cool bonus and apparently according to other reviews the battery will last for three years. I highly recommend. It was only £8.49!

La verdad es que llevo con el más de un año y sigue manteniendo la temperatura como el primer día. El uso es diario. Cabe destacar que yo lo limpio a mano.

La utilizzo per mantenere la temperatura dell’acqua a 70 gradi per il latte in polvere. Bellissimo il termometro per averlo più preciso basta metterlo in giù in modo che il liquido tocchi il tappo all’interno. Tiene per tantissime ore la temperatura. Approvatissimo

Bouteille isotherme vraiment très pratique je l'utilise tous les jours pour aller au travail tient vraiment bien au frais ou au chaud les deux fonctionne, l'indicateur de température est vraiment très pratique aussi elle est même fourni avec un petit filtre et une housse en néoprène. On a juste à passer le doigt sur l'écran et on connaît la température du liquide à l'intérieur de la bouteille. Je recommande vivement c'est super pratique !
