SIGG - Insulated Flask - Thermo Flask Hot & Cold ONE Light - With Fruit Filter - Leakproof - BPA-Free - 18/8 Stainless Steel - 0.55L

Only used it to keep water cold.Non spill, when locked.Single handed operation, which handy down the gym.Lid has a filter, so you can drop in peice of fruit to flavour your water.

I gave it as a birthday gift, the person was delighted as left the one he had on a flight and missed using it.

I'm really pleased with this purchase, my drinks stay hot for hours. I am even using a leaf tea, as the design of the bottle top doesn't let any bits to come out.

Excellent bottle keeps Tea hot for 6 hours which is period of time I've had a hot drink in it but I'm confident will be similar when I use it for longer periods.

Does as promised re keeping drinks hot or cold. Useful carry handle, one-hand flip top and nice drink spout. Recommend not leaving it empty with the top screwed on though - it gets smelly; fine if you leave the top off.

Really surprised by the amount of fails captured in this flask. Firstly it leaks and not just a little bit, i've tried reseating the rubber seal, tried placing the rubber seal the opposite way round but whatever I do will not stem the flow of liquid getting out into the environment you've placed the flask in.It even leaks between the lid and the plastic insert (Will come onto this shortly) so when you take a drink you also get an inconvenient shower at the same time.Then there's what looks like a plastic infuser (but isn't) with a spout, made of the same plastic they make selection boxes from and sat inside the lid with a rubber seal that might as well be made of chalk.Leaking aside this is then inserted at a 45 degree apposing angle to the opening mechanism on the lid which means upon opening the lid using your thumb you have to rotate the flask 45 degrees clockwise to take your drink!Why? Who designed this? Yes my wrist can make that turn as uncomfortable as it is but muscle memory dictates the drinking spout should be behind the lid clasp and until you get used to this change in expectation you better get used to your drink running down the side of your face.When you have got used to it expect it to run down your chin as it leaks. Honestly, just avoid, there's no upside at all.

We use for cycling take a hot drink during the ride (in winter). Keeps the drink hot, with no noticeable cooling. Does not fall out of a standard bike drinks holder either (though note quite tall) so a happy choice. Design pretty stylish too.

The bottle itself is nice, but the design of the lid is very poor. It is difficult to disassemble and reassemble for cleaning. The whole lid assembly is held in place by small, rigid, plastic tabs that look like they will break easily. Also, the drinking lip is too small and is awkwardly positioned, too close to the flat part of the lid.I have an older, non-insulated SIGG bottle that I have been using for at least 15 years on my travels in many countries and on hundreds of hikes etc. It is simple, well-designed and looks like it will go on for many years to come. It is one of my most reliable pieces of equipment. I hope SIGG will return to making that kind of well-designed, long-lasting product. That was the original appeal of the brand.
