Pioneer Flasks Double-wall Vacuum Travel Flask Hot and Cold Drink Bottle 350ml 0.35L, Stainless Steel, Silver

It does exactly what it says, very reliably. I've never known it to fail either in terms of insulation or leakage, and it's pretty robust as I've chucked it in the bottom of rucsacks whilst camping and even dropped it from my mountain bike, it still works the same.

This is a great thermos, it will keep a (tall dimension, if you are a starbucks fan) drink very warm for a very long time. On a long car trip, my coffee was still hot 6 hours later! It is also sized as a normal paper cup, so it will fit in your car's cup-holders and side doors.The drink clasp closes securely with little effort and holds in place when opened. It is not easy to spill.Awesome!

I thought the lid looked a bit dodgy, as it`s just a clip, rather than the usual Russian doll-like number of screwing lids that most flasks have. Absolutely no leakage though, so that`s the most important thing sorted. I`ve reviewed the small version, so it doesn`t hold much more than my usual tea mug, but it was perfect temperature four hours later, and also there wasn`t a hint of the taste of the flask (some flask do tend to change the flavour of the liquid). I think it looks very nice in steel and is very easy to wash. I like it a lot.

Good flask keeps drinks hot for along time. Only hesitation is the lid, I hope the closing mechanism stays strong. It has a clip on, and also a drinks lid. If all stays well I would give it 5 stars.

I like these vacuum flask things because sometimes my office only has bad coffee and it's much better to have home-made coffee and not spend a fortune at coffee shops.This looks like a very smart one - other than the 'travel flask' text, it's unbranded, and it's lightweight. The top has a 'snap top' which is basically a plastic hinge which closes firmly over the top, but that you can ping up again when you're ready.The 350ml version holds about the same as a small cup of coffee, so unless you're looking for something really small, I'd get the bigger one.However, heat does escape. I tested it multiple times and sometimes it'd be lukewarm after about four hours, sometimes it'd be hottish. I'm not really sure what I did differently, but it's obvious that some heat escapes through the plastic top somehow, even though the unit was closed at all times.If you're just using this to take your morning coffee to work, it'll do the job nicely until lunchtime. But if you're expecting boiling hot coffee in the mid to late afternoon, or going for a long walk and hoping it'll be drinkable eight hours later, I'd look elsewhere. It's a reasonable price and didn't leak on me, so if you fit into the right category, it's good.

A great product. When I received this it was larger than I was expecting, I'd imagined something similar in size to a Coke can.The simplicity of design lens itself to easy use with a clip-like lid that pops open easily yet, so far, has remained closed when not in use. It's easy to disassemble and clean (don't put in a dish washer) and reassemble.It keeps liquids warm for a long time (no I didn't time it) but it claims to work for up to 8 hours hot and up to 24 hours for cold liquids. I use this to carry warm drinks when out in the cold photographing.

This keeps the heat in a drink really well - lasts for hours. The flip-open tab makes drinking easy. The rippled outside makes it easy to hold onto. But..... this leaks! It is fine if kept upright but if you tilt it up the liquid leaks out into the 'join' between the cap and the body of the unit. When you then lower it, having taken a sip, it dribbles coffee, or whatever, down your chin and onto your shirt. So that is a major 'fail'. If is didn't leak it would be 5 stars but as it does leak 2 is quite generous.

I've now used this flask during a few road trips and am happy with the beverage storage device.It's a good size and keeps things nice and warm. That's the point, right? It's not something I'd ordinarily buy or use, so I've really only used it for the purposes of testing. You could take this on a plane, if you're happy to have 100ml of content or less in it to get through security, or want to fill it up afterwards. It seems best suited to road travel, though.The main reason I wouldn't use this is it actually can only hold about a mug of tea/coffee/whatever. If you have a short commute each day, this might be ideal. My star rating reflects the quality of the product and the price, though, as others will likely have different uses for the product than myself. If you can see yourself using this flask or need a new one, I can recommend this.

Lo compré de oferta, muy buena calidad y justo lo que necesitaba.
