This flask seems quite well-made and it looks good.However, it's primarily marketed as a tea infuser. There are some flaws in this concept:The flask needs to be kept vertical at all times prior to brewing, or water will enter the chamber and start brewing too early.Even kept vertical, steam from the hot water will enter the chamber and dampen the tea.The cap on the infuser could've been designed to also fit the flask without the infuser, or separate caps for the flask and both sides of the infuser, so that the infuser could be added when needed and the brewed tea capped in the flask for later consumption. As it is, you're stuck with the infuser on the flask, even after brewing the tea.The water pressure impedes the flow in & out of the infuser if the flask is turned upright, instead it needs to be tipped at an angle and it needs doing multiple times to ensure a good infusion, so you can't just invert the flask, stand it on its cap and leave it to brew.It doesn't stay hot enough to effectively brew tea all day.To its credit, it does contain loose tea very well, with very little working its way into the flask once brewed.If you're looking for a flask that you can put cold water in and infuse with fresh fruit, this is ideal. As a tea brewer, it's better to only add the tea at the point that you want to brew it, which rather negates its selling point. I think it's just easier to make the tea before you fill a regular flask with it.

TLDR: works as you would expect but be careful with spillages and possible scalds when very hotThis tea infuser is a clever idea. You put hot water in the bas/cup which is insulated so that it keeps hot. In the top compartment which separates from the bottom you can put tea leaves in. There is a mesh separator/strainer which keeps the leaves away from the water unless you invert the mug at which point the tea will brew. Re-invert and then the tea is ready to drink. Great idea.Obviously as a travel mug you can’t just sling the mug, when full, into a bag or anything as the mug if tipped will begin to brew so keeping it upright is important. Things I’ve also foundYou need to give the mug a bit of a shake when inverted to fill the chamber. And again when you reinvertInverting, shaking, reinverting is worth doing a couple of times tomget a nice brewAs the water is really hot air pressure can build up a bit so there is a risk that hot liquid is spat out when unscrewing the mug so take careAlso as you have wet leaves in the top of the mug you need to be aware of drips and spillages.Never the less, despite needing to use with a little caution this is a great idea and using quality leaves that are re-usable means that you can get a good couple of cups of tea on the go, or even just fill up and leave on your desk for when you are ready.When I reviewed this it was priced at £24.19 but there was also a 50% off voucher. At £24 it is a little overpriced in my honest opinion but at £12 it is a bargain.

I like the style, quality materials and smart finish of this bottle. However, the design does not seem to be very practical. The water migrates from the flask into the infuser compartment when the flask is tipped at an angle. So you must keep the flask vertical until you are ready to make the tea. At that point, turn the bottle upside down so that the water enters the infuser to mix with the tea leaves. This flask can then make a good brew.The vacuum flask is effective as the outside of the flask remains cool to the touch when I poured boiling water into the flask. However, the bottle as a whole with infuser and lid fitted does not appear to hold the heat so well. The boiling water loses enough heat after 5 hours that you cannot brew a decent flask of tea. The infuser is made from polypropylene which appears to get quite warm with hot water inside, and there is no thermal barrier between the infuser and vacuum flask.If you are are confident the bottle will remain upright until you are ready to make the tea, then this vacuum bottle may suit you. However, I think this product is quite expensive.

I am used to using a UK brand of bottle for iced water, which is phenomenal. Alas, this one is pretty poor. I filled it with iced water at mid-day and added some frozen fruit into the top portion to infuse the water. This seems an upside-down way to do it as you then have to actually turn the bottle upside down to get the infusion. The bottle fitted in the side door of the car where there is a cup holder cut-out. Even though it didn’t leak, there was constantly condensation on the outside of the bottle making it wet.At work two hours later the ice in the water had half melted and the drink was only cold rather than icy cold. Opening it only at hourly intervals, a further hour and all the ice had gone and the drink was beginning to warm up. At the four hour mark I had a drink which seemed to be at room temperature. I’m not impressed.

I have been using this over the last couple of days with loose black tea, the flask is well made and I have not experienced any leaks so far. I simply filled the top section with my loose tea, put boiling water into the main flask, screwed the infuser on and left it upside down to brew for a few minutes.One thing to note is that the holes that let the water between the main flask and infuser are not the smallest, so if you're using loose tea of other ingredients with small particles they will find their way into the main flask. The advertising mentions using coffee grounds, these will almost certainly find their way through the holes so I'd stick to a cafetiere for coffee. I also noticed that to get the water to drain to and from the infuser it was a lot faster if I held the flask at an angle rather than just placing upside down on a surface.Overall a solid tea infuser for when you're on the go. It's a little on the pricey side, especially when it only holds 400mL so you're only really getting one drink out of it.
