Review: Great - Firstly this is not a bottle that electronically keeps your water cool or hot drinks warm. In other words, it’s not for setting a temperature and then it stays like that. That’s quite a common misconception about these things. Really it’s just a flask with a digital readout! So fill it with cold juice or water and it’ll stay cool for hours but you’ll notice the temperature creep up from say 10 degrees every hour by a few degrees. It glows blue to show there’s a cold drink inside. Normal temperature shows green. Put hot water in or tea or coffee and you’ll see the indicator ring glow red and show a high temperature. I put boiling water in it as a test and it showed as 99 degrees which is correct. Technically boiling point is 100c but the readout can only show two figures therefore 99 will do. It very slowly crept down and six hours later it was 80 something. I made a cup of tea in it with milk so the temperature was around 86 at the point of brewing. Four hours later and I was still drinking it really hot. You won’t get beyond six hours of protection with this but it’s really good. I wish it was bigger because it only holds around 400ml which is two average cups of tea I’d say. So remember this is just a posh flask, not one of those things that keeps your tea at a steady temperature. I still recommend this highly
Review: 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

### ⭐⭐⭐⭐ Temp display broken, good size and good flask
*by A***R on 11 February 2026*

Good flask, bought for keeping water hot for babies bottles when out side and does stay above 70° for around 4-5 hours depending how many times it’s opened. The temperature display stopped working after a couple of months though which is a shame. Has never leaked in the 4 months we’ve used it, and is a nice size for keeping in babies changing bag.
